A copper-catalyzedoxidative cleavage reaction of alkynes using NFSI and TBHP was described. Various terminal and internal alkyne substrates were employed to render quick access to aryl ketone products in moderate to good yields. NFSI not only functioned as N-centered radical precursors but also engaged in the aryl group migration. Mechanistic studies also suggested the important role of water in the

photolysis. An electrontransfer reaction from the borate or the gallate counteranion to the excited triplet state of the benzophenone moiety (BP*3) was demonstrated. This reaction leads to the formation of benzophenone radicalanion (6) and the boranyl radical, the latter of which dissociates rapidly to form butyl radical. The electrontransfer rate was found to depend on the polarity of the solvent. In neat
