Copper(II) chloride and palladium(II) acetate were found to be highly effective catalysts for oxidative cleavage of O-benzylidene ring with t-butyl hydroperoxide. Using the former catalyst 4,6-O-benzylidenehexopyranoside derivatives were converted into the corresponding 4- and 6-benzoates in high yields. This reaction was also applicable for conversion of benzyl group into benzoyl one.
