The formation of benzylic hydroperoxides was shown to be a viable synthetic objective by their cleavage to oxygenated species in moderate, unoptimized yields. Oxidation of benzylic anions of metal arene complexes to oxygenated derivatives such as an alcohol, ketone or hydroperoxide are satisfactory target derivatives for this study. Oxidation of the benzylic anion of hexamethylbenzenechromiumtricarbonyl using a phenyl tosyloxaziridine and with chromium pentoxide gave low yields of the desired products. Electrochemical oxidation of a related iron complex anion in the presence of oxygen resulted in metal rather than anion oxidation. The cycloaddition reactions previously reported were extended but a reaction with an isocyanate gave several unidentified products. Attempted rhodium insertion in a phenyl-benzylic carbon-carbon bond resulted in aryl carbon-hydrogen insertion and ultimately formation of a Rh/sub 2//sup +4/ dimeric complex.
