Primary target: A practical and effective copper‐catalyzed amination strategy for synthesizing various benzylic amines from benzylic hydrocarbons is described (see scheme; DCE=1,2‐dichloroethane). Xylene substrates can undergo diamination reactions using this method. The remarkable preference for primary over secondary benzylic CHbonds has been observed for the first time.

Palladium-catalyzed inter- and intramolecular hydroaminations of styrenes that are coupled to alcohol oxidation under oxidative condition are reported. The fluorination reagent NFSI is used as the nitrogen source as well as the oxidant. Bidental nitrogen ligand bathocuproine plays a crucial role in this transformation. (C) 2010 Elsevier B.V.
