Provided is a method for the alcoholysis of an amide. The method comprises subjecting an amide-containing compound to alcoholysis under alkaline conditions using an epoxy compound as an accelerant of alcoholysis.
A nickel-catalyzed three-component coupling reaction between perfluoroarenes and two molecules of a 1,3-diene in the presence of an alkyl Grignardreagent, which acted as a hydride source, provided 3-perfluoroarylated-1,7-octadienes via 1,3-diene dimerization and subsequent perfluoroarylation upon C–F bond cleavage. The reaction proceeded smoothly in a regioselective manner by simply combining NiCl2
