the results. The decomposition and equilibrium constants were evaluated. The oxidation products were identified. The isokinetic temperature was 360 K, indicating the enthalpy to be a controlling factor. The rate of oxidation increased in the order Phg-Phg > Ala-Ala > Val-Val > Leu-Leu > Gly-Gly. The kinetics of oxidation of dipeptides was compared with those of their corresponding monomer amino acids

Kinetics of oxidation of thiosemicarbazide (TSC) by chloramine-B (CAB), and bromamine-B (BAB) in aqueous perchloric acid medium and by dichloramine-B (DCB) in 1:1 (v/v) water-methanol medium has been studied. The rate followed first order kinetics in [oxidant] and inverse fractional order in [H+] with all the oxidants. But it was fractional order in [TSC] with CAB and independent of [TSC] with BAB

The kinetics of oxidation of sulfanilic acid (SAA) by chloramine-B (CAB) and bromamine-B (BAB) has been investigated in alkaline medium at 35 ± 0.1°C. The oxidation reaction follows identical kinetics in the case of both the oxidants with first-order dependence on each [oxidant]o and [SAA]o and an inverse first-order dependence on [OH−]. The variation of ionic strength, dielectric constant of the medium

ides. The reaction has been shown to involve a nucleophilic attack by N-chlorosulphonamide ion on the epoxide; the nucleophilicity of this ion is comparable to that of azide. N-Bromobenzenesulphonamide behaves similarly but the instability of the product precludes an accurate assessment of the effect in this case. Two further examples of nucleophilic displacement by N-chloro-N-sodiosulphonamides are

A convenient method has been developed for the conversion of indoles and indigos into anthranilic acids in good to excellent yields using a bromamine-B/PdCl2 system. The general process utilizes our efficient method for the oxidation of indoles and indigos in alkaline (pH 12) acetonitrile/water (1:1) at 60 °C.
已经开发出一种使用溴胺-B/PdCl2 系统将吲哚和靛蓝转化为邻氨基苯甲酸的简便方法,收率非常好。一般工艺利用我们的有效方法在 60 °C 下在碱性 (pH 12) 乙腈/水 (1:1) 中氧化吲哚和靛蓝。
