Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate: A mild and efficient oxidant for oxidation of thiols, sulfides and aromatic amines to the corresponding disulfides, sulfoxides and azo compounds

Abstract

Bis(1-benzyl-4-aza-1-azoniabicyclo[2.2.2]octane) peroxodisulfate (BAABCPS) 1, readily prepared as orange solid from commercially available 1,4-diazabicyclo[2.2.2]octane (DABCO) and potassium peroxodisulfate converts thiols, sulfoxides and aromatic amines to the corresponding disulfides, sulfoxides and azo compounds respectively.
