Acetoxylation and Hydroxylation of Diarylmethylenecycloalkanes via Radical Approach

Diarylmethylenecycloalkanes were acetoxylated under the radical reaction conditions with PhI(OAc)2, I2, and TsNH2. Moreover, upon treating the products from the reactions of methylenecyclobutanes with N-bromosuccinimide (NBS) through silica gel column chromatography, the corresponding substituted methylenecyclobutanols were obtained in moderate to good yields. The plausible mechanisms have been proposed on the basis of the control experiments.
