An Improved Procedure for Oxidative Cleavage of Oximes to the Corresponding Carbonyl Compounds with Chromic Acid Supported on Kieselguhr under Viscous Conditions

An improved and efficient oxidative cleavage of oximes to the corresponding carbonyl compounds with chromic acid supported on kieselguhr reagent at room temperature under viscous conditions in the yield between 82% and 96% is described. The present procedure can overcome the problems that existed in the common solvent-free reactions as for the difficulty for the solid molecular collision to react.
