摘要

研究了重铬酸乙二铵在二甲亚砜中氧化伯醇的动力学。结果表明，所研究的醇都是按照相同的机理氧化的，都是由氢离子催化形成缺电子环过渡态，C2H4(NH4)2Cr2O7的反应顺序为1。主要的动力学同位素效应的存在表明醇类在反应过程中发生了C-H裂解（而不是C-C裂解）。

Kinetics of Oxidation of Aliphatic Primary Alcohols by Ethylenediammonium Dichromate in Dimethyl Sulfoxide

Kinetics of oxidation of primary alcohols by ethylenediammonium dichromate in dimethyl sulfoxide has been investigated. It is established that all studied alcohols are oxidized according to the same mechanism, which invlolves catalysis by hydrogen ions with the formation of electron-deficient cyclic transition state, and the reaction order for C₂H₄(NH₄)₂Cr₂O₇ is 1. The presence of primary of kinetic isotope effect indicates the C–H cleavage (not the C–C cleavage) in alcohols in the reaction process.
