Abstract
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.
