  with alkynyl trifluoroborates is described, proceeding through a cobalt hydride-mediated radical-polar crossover metal hydrogen-atom-transfer process. This method affords structurally diverse alkynyl-containing compounds in high yields under mild conditions and features a wide substrate scope, good functional group tolerance, and suitability for late-stage functionalization of relatively complex natural

  A new method for the synthesis of trifluoromethylated acetylenes is developed which involves the copper-catalyzed trifluoromethylation of alkynyltrifluoroborates with an electrophilic trifluoromethylating reagent. This method offers significant advantages such as efficiency and mild and base-free reaction conditions. A plausible mechanism is proposed. (c) 2012 Published by Elsevier Ltd.
