It has been found that the rates of oxidation of a variety of phenylcarbinols by manganese dioxide in benzene can be readily followed by noting the rate at which the by-product water distills into a Dean-Stark trap. The aldehydes and ketones produced are obtained in high yields and close to the theoretical volume of water is collected. The effects of changes in structure of the alcohols on their rates of oxidation are consistent with the proposal that the reaction proceeds via free radical intermediates. Aliphatic alcohols underwent oxidation much more slowly and in much lower yields than did the phenylcarbinols.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
