On April 30, 1994, Houalla, Douraid; Bounja, Zouhair; Skouta, Said; Wolf, Robert; Jaud, Joel published an article.SDS of cas: 2160-93-2 The title of the article was Macrocycles containing bicyclophosphorane moieties. And the article contained the following:

The first stable macrocycles, e.g. I (R = CMe3, Ph), containing pentacovalent phosphorus have been obtained by an Atherton-Todd reaction between the bis(hydridobicyclophosphoranes) with the corresponding binucleophile HO(CH2)2X(CH2)2OH. The tricyclic monophosphoranes II (X = O, NBu, NCMe3, NPh) as well as the noncyclic derivative III have also been isolated. A pathway that accounts for the formation of all these compounds is proposed. The x-ray crystal study of 2 16-membered rings, I (R = CMe3, Ph), confirms the diequatorial placement of the macrocyclic frame on the trigonal bipyramidal phosphorus which retains the most favorable axial-equatorial-axial annelation of the bicyclic moiety. Comparison of these 2 mol. structures points out the effect of the nature of X on the conformation of the macrocycle. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).SDS of cas: 2160-93-2

Abdel; Abbasi, Mohamed M. published an article.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was The behavior of N-tert-butyl-2,2′-iminodiethanol towards some trivalent phosphorus compounds. And the article contained the following:

Treating (HOCH2CH2)2NCMe3 (I) with PCl3 or HMPT in C6H6 gave the 2:3 adduct II, which was hydrolyzed by H2O to give the dioxazaphosphocane oxide III (R = H) (IV) and I. Treating IV with o-chloranil gave a crystalline product which in solution gave an equilibrium mixture of V (R = OH) and III (R = OC6Cl4OH-2). PhPCl2 or (Me2N)2PPh reacted with I to give dioxazaphosphocane VI, which added o-chloranil to give an equilibrium mixture of VII and V (R = Ph). Treating VI with PhN3 gave the imine VIII.

On April 30, 2011, Grabau, Mathias; Forster, Johannes; Heussner, Kirsten; Streb, Carsten published an article.Formula: C8H19NO2 The title of the article was Synthesis and Theoretical Hirshfeld Analysis of a Supramolecular Heteropolyoxovanadate Architecture. And the article contained the following:

A supramol. heteropolyoxovanadate structure was synthesized and characterized using single-crystal XRD, powder XRD and a range of spectroscopic methods. The new compound, [tBuNH(C2H4OH)2]4[H5P1V14O42]·12H2O (1) was obtained using a 1-pot strategy starting from a simple inorganic V oxide precursor and an amphiphilic cation in acidic aqueous solution The cluster anion [H5P1V14O42]4- is based on the known Keggin structure but in addition features two capping vanadyl [V=O]3+ units. In the crystal lattice, the clusters are arranged in linear 1-dimensional chains where neighboring clusters are directly linked by one H bond. The assembly is stabilized by lattice H2O mols. and organic counterions which aggregate to form hydrophobic cavities with diameters of 0.6 nm. To analyze the supramol. interactions leading to the cluster formation, the authors used a combination of traditional structural anal., theor. bond valence sum (BVS) calculations and computational Hirshfeld surface analyses which allow the rapid determination of short- and long-range intermol. contacts. The applicability of the Hirshfeld anal. tool for complex ionic compounds is evaluated and the advantages as well as the limitations of the method are discussed. The combination of these techniques allowed the authors to assess the dominating intermol. interactions and showed that the crystal packing is not only controlled by electrostatic interactions, but also by distinctive sets of H bonds and hydrophobic interactions between adjacent organic counterions. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Formula: C8H19NO2

On November 7, 2012, Manos, Manolis J.; Moushi, Eleni E.; Papaefstathiou, Giannis S.; Tasiopoulos, Anastasios J. published an article.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was New Zn2+ Metal Organic Frameworks with Unique Network Topologies from the Combination of Trimesic Acid and Amino-Alcohols. And the article contained the following:

New Zn2+-trimesate (btc3-) metal organic frameworks (MOFs) were isolated in the presence of various amino-alcs. under solvothermal conditions. Thus, the reaction of ZnCl2 with trimesic acid (H3btc) and the amino alcs. triethanolamine (teoa), 2-(hydroxymethyl)piperidine (hmpip), N-tert-butyldiethanolamine (tbdeoa), 1,4-bis(2-hydroxyethyl)piperazine (bhep), N-methyldiethanolamine (mdeoa), or 4-(2-hydroxyethyl)morpholine (hem) in a 1.6:1:5.6 molar ratio in DMF afforded compounds (teoaH)2[Zn(btc)1.33] (MOAAF-1) (MOAAF = metal organic amino-alc. framework), (NH2Me2)2(hmpipH)[Zn3(btc)3] (MOAAF-2), (NH2Me2)(tbdmaH)2[Zn3(btc)3] (MOAAF-3) (tbdma = N-tert-butyl-dimethylamine), (NH2Me2)(bhepH2)[Zn3(btc)3] (MOAAF-4), (NH2Me2)[Zn4(btc)3(mdeoa)2] (MOAAF-5), and (NH2Me2)[Zn4(btc)3(hem)2] (MOAAF-6), resp. The compounds display 3-dimensional structures with relatively large cavities (4-10 Å) and high potential solvent-accessible areas (38-68% of the unit cell volumes). A number of novel structural features are revealed in the reported MOFs, such as unprecedented dinuclear [Zn2(COO)5]-1 secondary building units (SBUs) and unique network topologies (e.g., in compounds MOAAF-2, MOAAF-3, MOAAF-5, and MOAAF-6). The amino-alcs. employed played a key role for the appearance of such novel structural features in MOAAF 1-6 since they act as bases responsible for the deprotonation of H3btc, templates, and chelating ligands. Specifically, most of the compounds synthesized are templated by protonated amino-alcs. that are involved in H bonding interactions with the frameworks, whereas in two cases (compounds MOAAF-5 and MOAAF-6) the amino-alcs. acted as chelating ligands affecting significantly the underline topol. of the MOFs. The thermal stability and photoluminescence properties of the MOFs are also discussed. This work represents the initial systematic study on the use of combination of amino-alcs. and polycarboxylate ligands for the synthesis of new MOFs, demonstrating it as a powerful synthetic strategy for the isolation of novel MOFs.

On November 24, 2009, Mereacre, Valeriu; Ako, Ayuk M.; Akhtar, Muhammad Nadeem; Lindemann, Anja; Anson, Christopher E.; Powell, Annie K. published an article.Electric Literature of 2160-93-2 The title of the article was Homo- and Heterovalent Polynuclear Cerium and Cerium/Manganese Aggregates. And the article contained the following:

Reactions of CeIII(NO3)3·6H2O or (NH4)2[CeIV(NO3)6] with Mn-containing starting materials result in seven novel polynuclear Ce or Ce/Mn complexes with pivalato (tBuCO2-) and, in most cases, auxiliary N,O- or N,O,O-donor ligands. With nuclearities from 6-14, the compounds present aesthetically pleasing structures. [CeIV6(μ3-O)4(μ3-OH)4(μ-O2CtBu)12] (1), [CeIV6MnIII4(μ4-O)4(μ3-O)4(O2CtBu)12(ea)4(OAc)4]·4H2O·4MeCN (ea- = 2-aminoethanolato; 2), [CeIV6MnIII8(μ4-O)4(μ3-O)8(pye)4(O2CtBu)18]2[CeIV6(μ3-O)4(μ3-OH)4(O2CtBu)10(NO3)4] [CeIII(NO3)5(H2O)]·21 MeCN (pye- = pyridine-2-ethanolato; 3), and [CeIV6CeIII2MnIII2(μ4-O)4(μ3-O)4(tbdea)2(O2CtBu)12(NO3)2(OAc)2]·4 CH2Cl2 (tbdea2- = 2,2′-[tert-butylimino]bis[ethanolato]; 4) all contain structures based on an octahedral {CeIV6(μ3-O)8} core, in which many of the O-atoms are either protonated to give (μ3-OH)- hydroxo ligands or coordinate to further metal centers (MnIII or CeIII) to give interstitial (μ4-O)2- oxo bridges. Decanuclear [CeIV8CeIIIMnIII(μ4-O)3(μ3-O)3(μ3-OH)2(μ-OH)(bdea)4(O2CtBu)9.5(NO3)3.5(OAc)2]·1.5 MeCN (bdea2- = 2,2′-[butylimino]bis[ethanolato]; 5) contains a rather compact CeIV7 core with the CeIII and MnIII centers well-separated from each other on the periphery. The aggregate in [CeIV4MnIV2(μ3-O)4(bdea)2(O2CtBu)10(NO3)2]·4 MeCN (6) is based on a quasi-planar {MnIV2CeIV4(μ3-O)4} core made up of four edge-sharing {MnIVCeIV2(μ3-O)} or {CeIV3(μ3-O)} triangles. The structure of [CeIV3MnIV4MnIII(μ4-O)2(μ3-O)7(O2CtBu)12(NO3)(furan)]·6 H2O (7·6 H2O) can be considered as {MnIV2CeIV2O4} and distorted {MnIV2MnIIICeIVO4} cubane units linked through a central (μ4-O) bridge. The Ce6Mn8 is the highest nuclearity yet reported for a heterometallic Ce/Mn aggregate. In contrast to most of the previously reported heterometallic Ce/Mn systems, which contain only CeIV and either MnIV or MnIII, some of the aggregates presented here show mixed valency, either MnIV/MnIII (see 7) or CeIV/CeIII (see 4 and 5). Some of the compounds, including the heterovalent CeIV/CeIII 4, could be obtained from either CeIII(NO3)3·6 H2O or (NH4)2[CeIV(NO3)6] as starting material.

On November 25, 2020, Davaritouchaee, Maryam; Chen, Shulin; Mancini, Rock J. published an article.Category: alcohols-buliding-blocks The title of the article was Delignification and Enzyme-Diffusion Kinetics of Radical Systems Treating Wheat Straw. And the article contained the following:

Biomass pretreatment is often evaluated based on the degree of delignification and the yield of enzymic hydrolysis. Thus, the phase delignification and enzyme diffusion kinetics models were utilized to describe the deconstruction mechanism of wheat straw treated with two-step radical oxidation The oxidation started with a superoxide radical anion, followed by a second radical treatment that synergizes the advantages of both radical systems. Two-step superoxide radical anion and two-step superoxide-hydroxyl radical pretreatments were the most effective pretreatment based on the degree of lignin removal and sugar release. These treatments resulted in 65 and 46% decrease in lignin content and 85.75 and 73.96% increase in glucan recovery, resp. The delignification kinetics constants, k1, k2, and k3, were found to be 1.950, 1.085, and 1.085 min-1, resp., for two-step pretreatment with superoxide radicals and 1.094, 0.717, and 0.717 min-1 with superoxide-hydroxyl radical pretreatment, whereas the kinetics constants were 0.485, 0.390, and 0.390 min-1 for the control. The structural diffusion resistance constant, n, was 0.205-0.359 for the control and 0.185-0.305 for the one-step superoxide treatment, 0.114-0.304 for two-step superoxide treatment, and 0.179-0.249 for two-step superoxide-hydroxyl radical treatment. These results justify that high lignin removal does not always contribute to a better enzymic hydrolysis rate, likely because oxidized lignin products on the surface of biomass can restrict enzyme accessibility. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Category: alcohols-buliding-blocks

On May 28, 2010, Mereacre, Valeriu; Akhtar, Muhammad Nadeem; Lan, Yanhua; Ako, Ayuk M.; Clerac, Rodolphe; Anson, Christopher E.; Powell, Annie K. published an article.Application In Synthesis of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Structures and magnetic properties of MnIII4LnIII4 aggregates with a “square-in-square” topology. And the article contained the following:

The structures and magnetic properties of a family of new octanuclear heterometallic 3d-4f complexes [MnIII4LnIII4(μ3-OH)4(μ2,η1-X)4(O2CBut)8(t-bdea)4]·solv, where X = N3-, Ln = Y (1), Eu (2), Gd (3), Tb (4), Dy (5), Ho (6); X = OCN-, Ln = Dy (7); X = NO3-, Ln = Gd (8), Tb (9), Dy (10), Ho (11), Er (12); solv = MeCN or toluene, are reported. The metal topol. in the aggregates can be described as consisting of a Ln4-square inscribed in a Mn4-square. Complexes 1-7 are prepared by the reactions of t-butyldiethanolamine (t-bdeaH2) with a preformed hexanuclear manganese pivalate complex [Mn6], the resp. lanthanide salt and either NaN3 or NaNCO, while 8-12 are obtained from the direct reaction of Mn(OAc)2, Ln(NO3)3·xH2O and t-butyldiethanolamine. The magnetic properties of all the complexes were investigated using variable temperature magnetic susceptibility and magnetization measurements. Similar magnetic behavior was observed for compounds containing the same lanthanide, indicating that changing the bridging ligand X does not have a significant effect on the magnetic behavior. The TbIII and DyIII compounds 4, 5, 7, 9 and 10 all show frequency-dependent ac susceptibilities indicative of a slow relaxation of magnetization and are therefore considered as Single-Mol. Magnets.

A.; Jezierska, Julia published an article.Formula: C8H19NO2 The title of the article was A new member of CuII8 family: Synthesis, structure and magnetic properties of an octanuclear copper complex with N-tert-butyldiethanolamine. And the article contained the following:

A highly-nuclear copper complex [CuII8O(tBuDea)5(HtBuDea)Cl2][CuICl2]·2H2O (1) has been prepared in a one-pot reaction of copper chloride with N-tert-butyldiethanolamine in methanol in the open air. The structure of the complex was established by single-crystal x-ray anal. The octanuclear close-packed core of 1 belongs to the {M8(μ3-X)6(μ-X)7} mol. structure type. The ESI-MS spectroscopy confirmed the stability of the whole core in methanol solution From the ESI-MS and magnetic data the divalent oxidation state of all eight coppers in the Cu8 core is proposed. Electrochem. studies were undertaken to confirm the overall CuI/CuII composition of the complex. Thermogravimetric behavior was studied and disclosed that the complex 1 is stable until 150°. The magnetic investigations revealed a dominant antiferromagnetic coupling between copper centers within the octanuclear cation.

Xiao, H. X.; Frisch, K. C.; Hsu, G. S. L.; Al-Salah, H. A. published an article in 1991, the title of the article was Polyurethane ionomers.Recommanded Product: 2160-93-2 And the article contains the following content:

Two types of urethane ionomers (cationomers and anionomers) were prepared and their structure-properties relationships examined The mech. properties and glass transition temperatures (Tg) of urethane cationomers increased with decreasing mol. weight of the polyols, and increasing concentrations of quaternary ammonium ions and degree of quaternization. The mech. properties and Tg’s of the cationomers decreased when isophorone diisocyanate was substituted by MDI. Comparing a series of N-alkyldiethanolamine chain extenders in urethane cationomers N-methyldiethanolamine based cationomers exhibited the best properties. Both mech. properties and Tg’s of urethane anionomers increased with increasing ionic potential (Θ) or charge-to-distance ratio (q/a) in nontransition mono- and divalent metals based anionomers. However, no relationship between Θ or q/a and mech. properties of Tg’s could be established in the transition divalent metals-based anionomers. Some interesting applications of urethane ionomers in foams and coatings are discussed which showed many potential applications of urethane ionomers in various industries. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Recommanded Product: 2160-93-2
