NEW CARBONYL COMPOUNDS FROM DEHYDROGENATION OF P-CRESOL

Chemical one-electron-type oxidation of p-cresol with ferric chloride yielded a previously unreported diphenyl ether 4 and three new ketonic trimers 5, 6, and 7, the structures of which are related to Pummerer’s ketone 1,which was also formed in the reaction mixture as were the known compounds 2 and 3. When p-cresol was oxidized enzymatically by peroxidase and peroxide, 5 was the only new unknown compound which could be isolated. © 1969, American Chemical Society. All rights reserved.
