Abstract
A large number of aldoximes and ketoximes are oxidized by imidazolium dichromate (IDC) in a solvent medium dimethylsulphoxide. The kinetic dependence was observed unity with respect to oxidizing agent and less than unity with respect to reductants or substrates. Aldoximes are found to react with a faster rate as compared to ketoximes. The DSP equation of Pavelich – Taft was found fit for correlation of aldoximes. Carbon is attacked by chromate oxygen indicated by the positive and low values of polar reaction constants. It is because of steric hindrance by the alkyl group available there. Representative data of solvent media influence was studied on acetaldoxime and analyzed by Taft and Swain LSER equations. A suitable mechanism for this reaction has also been postulated.
