Abstract

A giant Pd cluster, Pd561phen60 (OAc) 180, has high catalytic activity for the selective oxidations of various primary allylic alcohols to the corresponding α, β-unsaturated aldehydes in the presence of molecular oxygen under mild reaction conditions. A Pd cluster anchored on TiO2 also catalyzes the above oxidations; the heterogeneous Pd561 cluster catalyst is easily separated from the reaction mixture and is reusable.
