Furuyama, Taniyuki published the artcileCationic axial ligands on sulfur substituted silicon(IV) phthalocyanines: improved hydrophilicity and exceptionally red-shifted absorption into the NIR region, SDS of cas: 2212-32-0, the main research area is sulfur silicon phthalocyanine hydrophilicity absorption.

Herein, we report the exceptionally red-shifted absorption of sulfur-substituted silicon(IV) phthalocyanines upon introduction of cationic axial ligands. The Q band was red-shifted to approx. 900 nm with improved hydrophilicity by the combination of peripheral sulfur substituents and axial ammonium ligands. One such phthalocyanine exhibited remarkable photocytotoxicity upon irradiation with NIR light (∼810 nm) in live cells.

Bole, Leonie J. published the artcileUntangling the Complexity of Mixed Lithium/Magnesium Alkyl/Alkoxy Combinations Utilised in Bromine/Magnesium Exchange Reactions, Quality Control of 2212-32-0, the main research area is lithium magnesium alkyl alkoxy bromine exchange reaction reactivity substitution; crystal structure mol lithium magnesium alkyl alkoxy complex preparation; alkoxides; bromine/magnesium exchange; lithium; magnesium; mixed-aggregates.

While it is known that the addition of Group 1 alkoxides to s-block organometallics can have an activating effect on reactivity, the exact nature of this effect is not that well understood. Here we describe the activation of sBu2Mg towards substituted bromoarenes by adding one equivalent of LiOR (R = 2-ethylhexyl), where unusually both sBu groups can undergo efficient Br/Mg exchange. Depending on the substitution pattern on the bromoarene two different types of organometallic intermediates have been isolated, either a mixed aryl/alkoxide [{LiMg(2-FG-C6H4)2(OR)}2] (FG = OMe; NMe2) or a homoaryl [(THF)4Li2Mg(4-FG-C6H4)4] (FG = OMe, F). Detailed NMR spectroscopic studies have revealed that these exchange reactions and the formation of their intermediates are controlled by a new type of bimetallic Schlenk-type equilibrium between heteroleptic [LiMgsBu2(OR)], alkyl rich [Li2MgsBu4] and Mg(OR)2, with [Li2MgsBu4] being the active species performing the Br/Mg exchange process.

Bechara, I. S. published the artcileUnusual catalysts for flexible urethane foams, Name: N2-(2-Hydroxyethyl)-N1,N1,N2-trimethyl-1,2-ethylenediamine, the main research area is polyurethane foam hydroxyethylethylenediamine catalyst; ethanolamine aminoethyl polyurethane catalyst.

Dabco T [trimethyl(hydroxyethyl)ethylenediamine] [2212-32-0] type catalysts are unusual in that they are able to promote allophanate and isocyanurate formation, depending upon the concentration of NCO groups. They are also unique among tertiary amines in their ability to equalize the rate of urea and urethane formation. When used as cocatalysts, they provide good indentation load deflection (ILD) and compression set. Too high a catalyst concentration will increase the ILD and resiliency while adversely affecting compression set due to excessive allophanate and biuret formation. When flexible foams are made using these catalysts, optimum properties are obtained at NCO index of 105-16, and tin (cocatalyst) level as low as possible.

Wong, Shaio Wen published the artcileCatalysis in competing isocyanate reactions, Category: alcohols-buliding-blocks, the main research area is polyurethane formation model reaction kinetics; phenyl isocyanate reaction kinetics butanol; tin catalyst isocyanate reaction butanol; amine catalyst isocyanate reaction butanol; water effect isocyanate reaction butanol.

The kinetics of the model reaction between PhNCO and BuOH for polyurethane formation was studied in MeCN at 50°. Effects of various catalysts, such as an organotin compound, dibutyltin dilaurate, and tertiary amines, Dabco, N,N,N’,N’,N”-pentamethyldipropylenetriamine (I), N,N’,N”-tris(3-dimethylaminopropyl)-3-hexahydrotriazine, and N,N,N’-trimethylaminoethylethanolamine, on the reaction rate and the formation of reaction products were studied. The resulting products using I as catalyst were Bu phenylcarbamate, Bu α,γ-diphenylallophanate, and tri-Ph isocyanurate. The presence of water in the reaction retarded the disappearance of NCO groups as well as the trimer formation.

Zhang, Xinfu published the artcileRatiometric fluorescent probes for capturing endogenous hypochlorous acid in the lungs of mice, Computed Properties of 2212-32-0, the main research area is ratiometric fluorescent hypochlorous acid.

Hypochlorous acid (HClO) is a promising diagnostic marker for inflammation and relevant diseases. Although many probes were previously developed for HClO imaging, the development of organ targeting probes is still lacking. Herein, we designed and synthesized a series of cyanine derivatives as ratiometric fluorescent probes to detect endogenous HClO in the lungs with inflammation. By installing diverse lipid chains and amino groups on cyanine, we identified that ClO1, with one n-octadecane chain and two 2-[[2-(dimethylamino)ethyl]methylamino]-Et groups, is a superior probe to target the lungs over other major organs in mice. ClO1 was able to sense both exogenous and endogenous HClO in A549 (human lung epithelial) cells through fluorescence ratiometric imaging. In a lipopolysaccharide (LPS)-induced lung inflammation mouse model, ClO1 effectively captured endogenous HClO in the lungs after i.v. administration. Overall, these cyanine-derived probes merit further development as organ targeting HClO sensors.

Mukherjee, Shreya published the artcileA variety of new tri- and tetranuclear Mn-Ln and Fe-Ln (Ln = lanthanide) complexes, Application In Synthesis of 2212-32-0, the main research area is manganese gadolinium carboxylate heterometallic cluster preparation crystal structure; iron gadolinium carboxylate heterometallic cluster preparation crystal structure; magnetic property iron manganese gadolinium heterobimetallic cluster; transition metal lanthanide carboxylate heterometallic cluster preparation crystal structure.

The use of carboxylates in the synthesis of 3d/4f clusters, with or without a second organic ligand, has afforded tetranuclear M2Gd2 complexes (M = Fe or Mn), and two new trinuclear M2Gd (M = Fe or Mn) mol. compounds Only one of these, [Mn2Gd2O2(O2CBut)8(HO2CBut)4] (1), does not contain a multidentate chelate ligand. Two other similar tetranuclear clusters were synthesized from the use of triethanolamine (teaH3) and 1,1,1-tris(hydroxymethyl)ethane (thmeH3). [Mn2Gd2(OH)2(O2CPh)4(NO3)2(teaH)2] (2) has very similar structure with 1, bearing a defective incomplete double-cubane core bridged by μ3-O atoms, whereas in the core of [NHEt3]2[Fe2Gd2(O2CPh)4(thme)2(NO3)4] (3) the thme3- ligand caps the two incomplete cubane units, providing the triply-bridging alkoxides needed for bridging. Two new oxide-centered triangular clusters were synthesized bearing the Schiff-based chelate 2-{[2-(dimethylamino)ethyl]methylamino}ethanol (dmemH), [Fe2GdO(O2CBut)2(dmem)2(NO3)3] (4), and [Mn2GdO(O2CBut)2(dmem)2(NO3)3] (5). Magnetic susceptibility measurements and/or reduced magnetization studies established that complexes 1 and 3 have an S = 5 ground state, complex 2 has S = 4, and complexes 4 and 5 are S = 7/2 in their ground states. These complexes portray the feasibility of obtaining products bearing metal cores commonly found in homometallic clusters, even when these include metals with completely different coordination chem. and electronic structure, such as lanthanides.
