Gold-Catalyzed Regioselective Dimerization of Aliphatic Terminal Alkynes
09 November 2011 (eFirst)
A gold-catalyzed regioselective homodimerization of aliphatic terminal alkynes is described. Bulky and less Lewis acidic t-BuXPhosAuNTf2 is the preferred catalyst, and the additive, anhydrous NaOAc, substantially facilitates the reaction.
