Abstract
Benzil derivatives are catalytically oxidized by the heteropolyacids of gen eral formula H3+nPMo12-nVnO40, xH(2)O (HPA-n, n = 1-4, x = 30-36) with diox ygen under mild conditions. High yields and excellent selectivity of mono- and dicarboxylic esters were obtained in the presence of primary alcohols o r diols.
