STUDIES IN BECKMANN REARRANGEMENT OF SUBSTITUTED BENZOPHENONE AND ACETOPHENONE OXIMES

Abstract

ABSTRACT The Beckmann rearrangement of substituted benzophenone and acetophenone oximes was effected using ‘silferc’ as catalyst, prepared by impregnating anhydrous FeCl3 on silica gel by co-grinding technique. Justification: The Beckmann rearrangement of substituted benzophenone and acetophenone oximes was effectively studied by using a novel catalyst prepared by co-grinding technique. The catalyst preparation eliminates the use of volatile organic solvents, which are used for impregnation thereby offering a ‘Greener alternative’. The reactions were carried out under milder conditions, the amount of catalyst required was catalytic and also showed reusability. ACKNOWLEDGMENT The authors are thankful to G. D. Gokhale trust for awarding fellowship to one of the authors.
