OXIDATION OF ALCOHOLS TO ALDEHYDES AND KETONES USING TBHP AS AN OXIDANT OVER LaMO3 (M = Cr, Mn, Co, Ni, Fe) PEROVSKITES

Oxidation of a wide variety of structurally and electronically diverse primary and secondary alcohols to aldehydes and ketones was carried out using a novel catalytic system of LaCrO3 and tert-butyl hydroperoxide (TBHP) under solvent-free conditions. The methodology afforded the desired carbonyl compounds in good to excellent yields, and the catalyst can be reused several times with no significant loss in activity.
