摘要：

Palladium(II) acetate catalyzes the aerobic oxidation of terminal alkenes in toluene into the corresponding methyl ketones in the presence of a catalytic amount of pyridine using propan-2-ol as a reductant and molecular oxygen as an oxidant. Two catalytic cycles sharing a Pd(II)-OOH species are proposed. One is the formation of a Pd(II)-H species in the oxidation of propan-2-ol to acetone, followed by reaction with molecular oxygen to give a Pd(II)-OOH species, and the other is peroxypalladation of an alkene with the Pd(II)-OOH species produced to afford a methyl ketone in the presence of H2O2 produced by the former catalytic cycle.
