SbCl5 Complexes of Pyridine N-Oxide and Trimethylamine Oxide as the Oxidizing Agent

Article abstract of DOI:10.1246/bcsj.55.345

A 1:1 complex of pyridine N-oxide or trimethylamine oxide with SbCl5 acted as an oxidizing agent to benzyl alcohol, benzoin, furoin, and thiophenols more easily than via the oxides to give benzaldehyde, benzil, furil, and the corresponding disulfides respectively.The trimethylamine oxide-SbCl5 also oxidized p-xylene to p-tolualdehyde under nitrogen and to p-toluic acid under air.
