Synthesis and Application of New Oxidantbis(banzyltriphenylphosphonium) peroxodisulfate on Oxidation ofBenzylhalides to Corresponding Benzylaldehyde Compounds

Put the peroxodisulfate ion (S۲O۸۲-) in the phase transfer catalyst banzyltriphenylphosphonium can make a catalyst withmild oxidation property, and used it for oxidation of Benzylhalides to corresponding Benzylaldehyde Compounds. Formaking catalyst used xylene and water as solvent, and it was an easy process with high yield. Oxidation used in refluxcondition with acetonitrile as solvent. The advantages of this oxidation:high yield and short time.
