Dual-function phase-transfer catalysis in the metal-assisted oxidation by hydrogen peroxide of styrene to benzaldehyde or acetophenone

Abstract

Quaternary ammonium salts assist the extraction of both hydrogen peroxide and metal salts, e.g. ruthenium or palladium chloride from the aqueous to the non-aqueous component of a two-phase system; the system has been used for the oxidation of styrene.
