Graton, J.; Besseau, F.; Goupille, A.; Le Questel, J.-Y. published the artcile< Hydrogen-bond acidity of silanols: A combined experimental and theoretical study>, Name: Triphenylmethanol, the main research area is quantum chem hydrogen bond acidity silanol.

The hydrogen-bond (H-bond) donating ability of a series of silanol derivatives has been determined by FTIR spectrometry and complemented by quantum chem. calculations at the DFT (MPWB1K/6-31+G(d,p)) level. The equilibrium constants of complexation with N-methylpyrrolidinone have been measured in CCl4 solutions These data expand the pKAHY scale previously covering the field of aliphatic alcs., phenols and fluorohydrins. Compared to the corresponding alc. derivatives, the silanol chem. function is a stronger H-bond donor, although the observed frequency shifts, ΔνOH, suggest much greater differences in donor strength than is actually observed The electrostatic potential descriptor, Vα(r), is successfully used to complete the pKAHY vs. Vα(r) relationship, a helpful methodol. to validate the exptl. data and to estimate the H-bond acidity of unavailable, unstable, or immiscible compounds

Yadav, Vishal; Gordon, Jesse B.; Siegler, Maxime A.; Goldberg, David P. published the artcile< Dioxygen-Derived Nonheme Mononuclear FeIII(OH) Complex and Its Reactivity with Carbon Radicals>, Formula: C19H16O, the main research area is neopentylamine dioxygen nonheme mononuclear iron hydroxide preparation reactivity carbon; carbon radical reactivity neopentylamine dioxygen nonheme mononuclear iron hydroxide; crystal mol structure neopentylamine dioxygen nonheme mononuclear iron hydroxide.

A new tetradentate, monoanionic, mixed N/O donor ligand (BNPAPh2O-) with second coordination sphere H-bonding groups has been synthesized for stabilization of a terminal FeIII(OH) complex. The complex FeII(BNPAPh2O)(OTf) (1) reacts with O2 to give a mononuclear terminal FeIII(OH) complex, FeIII(OH)(BNPAPh2O)(OTf) (2), both of which were characterized by x-ray diffraction, electrospray ionization mass spectrometry, UV-vis, 1H and 19F NMR, 57Fe Moessbauer, and ESR spectroscopies. Treatment of 2 with carbon radicals (Ar3C·) gives Ar3COH and the FeII complex 1, in direct analogy with the elusive radical “”rebound”” process proposed for nonheme iron enzymes.

Mulkapuri, Sateesh; Kurapati, Sathish Kumar; Das, Samar K. published the artcile< Carbonate encapsulation from dissolved atmospheric CO2 into a polyoxovanadate capsule>, Application In Synthesis of 76-84-6, the main research area is sodium polyoxovanadate carbonate chloride complex preparation encapsulation magnetic property; thermal stability sodium polyoxovanadate carbonate chloride; crystal structure sodium polyoxovanadate carbonate chloride.

An aqueous synthesis, involving the reduction of the VO3- anion in a mild alk. pH in the presence of α-Bi2O3, led to the formation of a fully reduced polyoxovanadate (POV) capsule, with CO32- anion encapsulation in its internal cavity, in the compound [Na6(H2O)24][H8VIV15O36(CO3)]·3N2H4·10H2O (1). This CO32- anion encapsulation, the source of which is absorbed aerial CO2 in the pertinent aqueous alk. reaction mixture, occurs only in the presence of α-Bi2O3. Compound 1 crystals, upon exposure to HCl acid vapor, exclude CO2 gas that can react with the Grignard reagent (PhMgBr) to form triphenylcarbinol and benzoic acid; during this solid-vapor interface reaction, compound 1 itself transforms into an amorphous material that includes the Cl- anion but could not be characterized unambiguously. Thus, we have synthesized a chloride ion (Cl-) encapsulated compound [Na10(H2O)24][H3VIV15O36(Cl)]·6H2O (2) in a direct synthesis protocol, which has been characterized by crystallog. as well as by other spectroscopic methods. Compounds 1 and 2, each having fifteen vanadium(IV) centers, exhibit interesting magnetism in their solid states. The temperature-dependent magnetic susceptibilities for compounds 1 and 2 have been recordred at 0.1 T at of 3-300 K. The temperature-dependent magnetic susceptibilities of compounds 1 and 2 are shown in the form of χM vs.T and their product χMT vs.T plots.

Di Berto Mancini, Marika; Del Gelsomino, Andrea; Di Stefano, Stefano; Frateloreto, Federico; Lapi, Andrea; Lanzalunga, Osvaldo; Olivo, Giorgio; Sajeva, Stefano published the artcile< Change of Selectivity in C-H Functionalization Promoted by Nonheme Iron(IV)-oxo Complexes by the Effect of the N-hydroxyphthalimide HAT Mediator>, Safety of Triphenylmethanol, the main research area is nonheme iron oxo complex hydroxyphthalimide hydrogen transfer hydrocarbon oxidation.

A kinetic anal. of the hydrogen atom transfer (HAT) reactions from a series of organic compounds to the iron(IV)-oxo complex [(N4Py)FeIV(O)]2+ and to the phthalimide N-oxyl radical (PINO) has been carried out. The results indicate that a higher activating effect of α-heteroatoms toward the HAT from C-H bonds is observed with the more electrophilic PINO radical. When the N-hydroxy precursor of PINO, N-hydroxyphthalimide (NHPI), is used as a HAT mediator in the oxidation promoted by [(N4Py)FeIV(O)]2+, significant differences in terms of selectivity have been found. Product studies of the competitive oxidations of primary and secondary aliphatic alcs. (1-decanol, cyclopentanol, and cyclohexanol) with alkylaroms. (ethylbenzene and diphenylmethane) demonstrated that it is possible to modify the selectivity of the oxidations promoted by [(N4Py)FeIV(O)]2+ in the presence of NHPI. In fact, alkylarom. substrates are more reactive in the absence of the mediator while alcs. are preferably oxidized in the presence of NHPI.

Wang, Yu-Heng; Yang, Qiaomu; Walsh, Patrick J.; Schelter, Eric J. published the artcile< Light-mediated aerobic oxidation of C(sp3)-H bonds by a Ce(IV) hexachloride complex>, Safety of Triphenylmethanol, the main research area is alc aldehyde ketone carboxylic acid preparation; alkane arene photochem oxygenation cerium hexachloride catalyst.

A photochem. C(sp3)-H oxygenation of alkane and arene substrates catalyzed by [NEt4]2[CeIVCl6] under mild conditions (1 atm, 25°C) is described. Time-course studies reveal that the hydrocarbons are oxidized in a stepwise fashion to afford alcs., aldehydes, ketones, and carboxylic acids. The catalyst resting state, [CeIVCl6]2-, is observed by UV-visible spectroscopy. On/off light-switching experiments, quantum yield measurements, and the absence of a kinetic isotope effect on parallel C-H/C-D functionalization suggest that ligand-to-metal charge transfer of [NEt4]2[CeIVCl6] to generate Cl is the turnover-limiting step. The involvement of a highly reducing excited-state [NEt4]3[CeIIICl6]* species as well as photo-excited aldehyde, under black light irradiation appears to facilitate the conversion of primary alcs. and aldehydes to carboxylic acids. Remarkably, this approach is found to be capable of direct activation of light alkanes, including methane and ethane.

Jin, Pengkang; Ren, Bo; Wang, Xiaochang C.; Jin, Xin; Shi, Xuan published the artcile< Mechanism of microbial metabolic responses and ecological system conversion under different nitrogen conditions in sewers>, Synthetic Route of 76-84-6, the main research area is microbial metabolic responses ecol system nitrogen condition sewer; Ecological system; Functional bioconversion; Metabolization response; Nitrogen source; Urban sewer system.

However, the mechanisms underlying the involvement of nitrogen-associated pollutants in sewer ecosystems remain unknown. In this study, the effects of two typical nitrogen ratios (organic/inorganic nitrogen: 7/3 (Group A) and 3/7 (Group B)) on carbon, nitrogen, and sulfur bioconversions were investigated in a pilot sewer. The distribution of amino acids, such as proline, glycine and methionine, was significantly different between Groups A and B, and carbon-associated communities (based on 16S rRNA gene copies) were more prevalent in Group A, while sulfur and nitrogen-associated communities were more prevalent in Group B. To explore the effect of nitrogen on microbial response mechanisms, metagenomics-based methods were used to investigate the roles of amino acids involved in carbon, nitrogen, and sulfur bioconversion in sewers. Proline, glycine, and tyrosine in Group A promoted the expression of genes associated with cell membrane transport and increased the rate of protein synthesis, which stimulated the enrichment of carbon-associated communities. The transmembrane transport of higher concentrations of alanine and methionine in Group B was essential for cell metabolism and nutrient transport, thereby enriching nitrogen and sulfur-associated communities. In this investigation, insights into carbon, nitrogen and sulfur bioconversions in sewer ecosystems were revealed, significantly improving the understanding of the sewer ecosystem within a community context.

Carbon-carbon bond formation through polarity reversal ketyl radical anion coupling of carbonyls has inspired new reaction modes to this cornerstone carbonyl group and played significant roles in organic chem. The introduction of this resplendent polarity reversal ketyl strategy into polymer chem. will inspire new polymerization mode with unpredicted discoveries. Here we show the successful introduction of polarity reversal ketyl approach to polymer chem. to realize self-condensing ketyl polymerization with polymerization-induced emission. In this polarity reversal approach, it exhibits intriguing reversed polymerizability, where traditional excellent leaving groups are not suitable for polymerization but challenging polymerizations involving the cleavage of challenging C-F and C-CF3 bonds are realized under mild Barbier conditions. This polarity reversal approach enables the polymer chem. with polarity reversal ketyl mode, opens up a new avenue toward the polymerization of challenging C-X bonds under mild conditions, and sparks design inspiration of new reaction, polymerization, and functional polymer.
