B2pin2-catalyzed oxidative cleavage of a CC double bond with molecular oxygen

Abstract

B₂pin₂-catalyzed oxidative cleavage of the CC double bond of an olefin with molecular oxygen as the oxidant and oxygen source has been developed. Various diaryl ketone, diketone, triketone and estrone derivatives were obtained in moderate to excellent yields. The NMP (N-methyl pyrrolidone)-stabilized B-centered radical species was proposed as a possible catalyst.
