Abstract

The mechanism for the oxidation of sulfides by [(me4-salen) CrV (O)(pyO)] CF3SO3, where me4-salen is 8, 8, 8', 8'-tetramethylsalen and pyO is pyridine N-oxide, has been investigated. Results from Hammett correlations on the rates of oxidation of substituted thioanisoles, frontier molecular orbital calculations, and product studies are consistent with a mechanism that is initiated by a single electron transfer to give a radical cation intermediate.
