The oxidation of benzaldehyde and thirty-five monosubstituted benzaldehydes by benzyltrimethylammonium tribromide (BTMAB) in aqueous acetic acid gives the corresponding benzoic acids. The reaction is first order with respect to each the benzaldehyde and BTMAB. The reaction failed to induce the polymerization of acrylonitrile. There is no effect of benzyltrimethylammonium chloride on the reaction rate. The oxidation of [²H]benzaldehyde (PhCDO) indicated the presence of a substantial kinetic isotope effect. The effect of solvent composition indicated that the reaction rate increases with an increase in the polarity of the solvent. The rates of oxidation of meta- and para-substituted benzaldehydes are correlated in terms of Charton’s triparametric LDR equation whereas the oxidation of ortho-substituted benzaldehydes are correlated with tetraparametric LDRS equation. The oxidation of para- substituted benzaldehydes is more susceptible to the delocalization effect than is the oxidation of ortho-and meta-substituted compounds, which display a greater dependence on the field effect. The pos. value of η suggests an electron-deficient reaction center in the rate-determining step. The reaction is subjected to steric hindrance by the ortho-substituents.

Sankhla, Rekha published the artcileCorrelation analysis of reactivity in the oxidation of substituted benzylamines by benzyltrimethylammonium tribromide, Product Details of C10H16Br3N, the publication is Indian Journal of Chemistry, Section A: Inorganic, Bio-inorganic, Physical, Theoretical & Analytical Chemistry (2002), 41A(3), 541-546, database is CAplus.

The oxidation of benzylamine and twenty-seven ortho-, meta- and para-monosubstituted benzylamines by benzyltrimethylammonium tribromide (BTMAB), in dimethylsulfoxide (DMSO), gives corresponding aldimines. The reaction is first order with respect to both BTMAB and the amine. The oxidation of deuterated benzylamine exhibited a substantial kinetic isotope effect. Addition of benzyltrimethylammonium bromide does not affect the rate. Tribromide ion was postulated as the reactive oxidizing species. The rates of the oxidation of para- and meta-substituted benzylamines showed excellent correlation in terms of both Taft’s dual substituent-parameter and Charton’s triparametric LDR equations, whereas the ortho-substituted compounds exhibited the best correlation with the Charton’s tetraparametric LDRS equation. The oxidation of para-substituted benzylamines is more susceptible to the delocalization effect than is the oxidation of ortho- and meta-substituted compounds, which display a greater dependence on the field effect. The low pos. value of the η suggests an electron-deficient center in the rate-determining transition state with less charge separation A suitable mechanism was proposed.

The oxidation of formic and oxalic acids by benzyltrimethylammonium tribromide (BTMAB) leads to the formation of carbon dioxide. The reaction is first order with respect to BTMAB. Michaelis-Menten type kinetics are observed with respect to substrate. The values of the formation constants for the organic acid-BTMAB complexes and the rates of their decomposition, at different temperatures, have been determined Oxidation of α-deuterioformic acid indicated the presence of a primary kinetic isotope effect (k_H/k_D = 6.03 at 298 K). With an increase in the polarity of solvent, the formation constants for the complexes decrease however, their rates of decomposition increase. Suitable mechanisms involving the formation of acyclic and cyclic intermediates in the oxidations of formic and oxalic acids resp., have been proposed.

Erickson, Paul R. published the artcilePhotochemical Formation of Brominated Dioxins and Other Products of Concern from Hydroxylated Polybrominated Diphenyl Ethers (OH-PBDEs), Safety of Mono(N,N,N-trimethyl-1-phenylmethanaminium) tribromide, the publication is Environmental Science & Technology (2012), 46(15), 8174-8180, database is CAplus and MEDLINE.

The photochem. conversion of selected hydroxylated polybrominated di-Ph ethers (OH-PBDEs) to dioxins and other products was investigated. OH-PBDEs, which are both transformation products of polybrominated di-Ph ethers and naturally occurring compounds, undergo direct photolysis to yield a number of products that may have a higher toxicity than their parent. The compounds investigated were 6-OH-PBDE 99, 6′-OH-PBDE 100, and 6′-OH-PBDE 118. Of special interest was 6′-OH-PBDE 118, a potential transformation product of PBDE 153 that is capable of photochem. generating 2,3,7,8-tetrabromodibenzo-p-dioxin, the most toxic brominated dioxin congener. Photolysis experiments were conducted at two different pH values to assess the photochem. behavior of both the phenol and phenolate form of the compounds The percent conversion to dioxin and other photoproducts was determined and the natural product, 6-OH-PBDE 99, was found to have the highest conversion to dioxin (7%). The reaction quantum yields ranged from 0.027 to 0.16 across all photolysis conditions. In addition, it is shown that all three compounds are capable of photochem. generating other compounds of concern, including brominated phenols and a dibenzofuran.

The reaction of bis(carbene) complexes with bis(alkyne)s in a triple annulation provides direct access to homocalixarenes with three and four aromatic rings. Through proper choice of tether length, these macrocycles were assembled with ring sizes ranging from 15 to 56 carbon atoms. This method allows full control over the ring size and symmetry, and its ability to provide the synthesis of a series of all-homocalixarenes was illustrated for compounds having 2,3,5 and 11 methylene linkers between each ring. This method is also flexible enough to allow the incorporation of a pyrrole unit in place of one of the benzene rings in the calixarene. The macrocycles are always isolated as a single product and can be prepared conveniently on a gram scale. Six of the twelve homocalixarenes that were prepared were characterized by single-crystal x-ray anal.

Suryachandra published the artcileKinetics and mechanism of the oxidation of phosphinic, phenylphosphinic and phosphorous acids by benzyltrimethylammonium tribromide, SDS of cas: 111865-47-5, the publication is Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry (1998), 37B(11), 1129-1132, database is CAplus.

The oxidation of phosphorus-(I) and -(III) oxyacids by benzyltrimethyl ammonium tribromide (BTMAB), in 9:1 (volume/volume) acetonitrile-acetic acid, leads to the formation of corresponding phosphorus-(III) and -(V) oxyacids. The reaction is first order with respect to each of the BTMAB and oxyacid. There is no effect of benzyltrimethylammonium chloride or bromide ion on the reaction rate. The oxidation of deuterated phosphinic and phosphorous acids exhibit the presence of a substantial kinetic isotope effect. The rate decreases with an increase in the proportion of acetic acid in the solvent. It has been shown that the reactive reducing species is the penta-coordinated form of the oxyacid. Tribromide ion has been postulated as the reactive oxidizing species. A mechanism involving a hydride-ion transfer in the rate-determining step has been proposed.

Yamato, Takehiko published the artcileMedium-sized cyclophanes. Part 57. Synthesis, conformations and stereodynamics of [2.n]metacyclophan-1-enes and their conversion to [2.n]metacyclophan-1-ynes, Application In Synthesis of 111865-47-5, the publication is New Journal of Chemistry (2001), 25(5), 728-736, database is CAplus.

Anti- and syn-[2.8]Metacyclophan-1-enes I, which are both conformationally rigid structures, were prepared in good yields by a McMurry cyclization of 1,8-bis(5-tert-butyl-3-formyl-2-methoxyphenyl)octane. Similarly, McMurry cyclization of 1,10-bis(5-tert-butyl-2-methoxy-3-formylphenyl)decane afforded (E)- and (Z)-[2.10]-metacyclophan-1-enes II in good yields. The assignment of the E and Z structures was confirmed by ¹H-NMR analyses and single crystal X-ray diffraction studies. Bromination of (E)- and (Z)-II with benzyltrimethyl- ammonium tribromide affords exclusively the cis-adduct to the bridged double bond. When treated with potassium tert-butoxide in refluxing tert-BuOH at 80°C for 3 h, the bromine meso adduct gave the dehydrobrominated product [2.10]metacyclophan-1-yne in 93% yield, along with a 1-bromo[2.10]metacyclophan-1-ene in 7% yield; the same reaction with the dl-bromine adduct from II gave 29% of [2.10]metacyclophan-1-yne along with 71% of the 1-bromo[2.10]metacyclophan-1-ene. Similarly, anti- and syn-[2.8]metacyclophan-1-ynes were also prepared by bromination of syn-[2.n]metacyclophan-1-ene syn-I, followed by the dehydrobromination of the bromine adduct. The characterization and the reaction pathway of these products are discussed. The dynamics of the ring inversion and UV spectra are also presented.
