Abstract

Heteropolyacids H_3+nPMo_12-nV_nO₄₀ (HPA-n, n = 1-4) catalyze efficiently the oxidation and the oxidative cleavage of benzoin derivatives in the presence of dioxygen. HPA-2 gave the highest total yields in aldehydes and carboxylic esters by using primary alcohols as solvents. No oxidative cleavage products were obtained with secondary or tertiary alcohols. HPA-2 catalyzes the oxidation of benzoin to benzil in the presence of t-BuOH or other polar solvents such THF, CH₃CN, DME.
