Facile oxidation of aldehydes to esters using S center dot SnO2/SBA-1-H2O2
A highly efficient, mild, and simple procedure has been described for the oxidation of aldehydes to corresponding esters in alcohols with S.SnO2/SBA-1 as catalyst and H2O2 as the oxidant, and the catalytic systems can be used in the preparation of a broad range of esters. Oxidation of aldehydes to corresponding esters utilizing H2O2 as the oxidant without any metal catalyst is also reported.
