30 - 048Palladium(II)-Catalyzed Oxidative Ring Cleavage of tert-Cyclobutanols under Oxygen Atmosphere. — A novel palladium-catalyzed reaction of several tert-cyclobutanols involving selective β-carbonelimination of a palladium alcoholate intermediate under aerobic conditions isreported. In some cases, the product of the β-carbon elimination undergoes insitu cyclization to furnish cyclic ketones [cf. (VI), (VIII)]. — (NISHIMURA,TAKAHIRO; OHE, KOUICHI; UEMURA, SAKAE; J. Am. Chem.
