Abstract

The homogeneous decatungstate W10O324-catalyzed photooxygenation of 1, 1- diphenylethane and 9-methyl-9H-fluorene has been studied mechanistically. The primary and β-secondary kinetic isotope effects provide strong evidence for a stepwise mechanism, with a hydrogen atom abstraction in the rate-determining step.
