Relative reactivities of glucopyranosides towards permanganate and chromic acid in perchloric acid medium

Department of Chemistry, Jadavpur University, Kolkata-700 032, India Manuscript received 8 August 2000, revised 19 January 2001. accepted 2 February 2001 The oxidative behaviour and relative reactivity of methyl-α-D-glucopyranoside and methyl-β-o-glucopyranoside towards permanganate and acid chromate have been studied in perchloric acid medium. The reactions are first order with respect to [glucopyranoside] and [oxidant]. The reaction rates increase with the increase in [H+]. Activation parameters of the reactions have been evaluated. The mechanism of the reactions has been discussed.
