Abstract

A novel combination of Pd (OAc) 2/pyridine/MS3A catalyzes the aerobic oxidation in toluene of a variety of primary and secondary alcohols into the corresponding aldehydes and ketones in high yields. Various substituents and protecting groups are compatible with this oxidation. The ca. 2: 3 ratio of O2 uptake to product yield is observed, whereas in the absence of MS3A, the ratio is ca. 1: 1, suggesting the in situ formation of H2O2 and its ...
