AminationO 0268 A Cationic Gold(I) Complex as a General Catalyst for the Intermolecular Hydro-

amination of Alkynes: Application to the One-Pot Synthesis of Allenes from Two Alkynes and a Sacrificial Amine. — A gold(I) catalyst containing a bulky cyclic car-bene ligand readily promotes the hydroamination of various terminal and internal al-kynes with primary and secondary amines. Enamines thus generated from alkynes and secondary amines can undergo a further hydroamination reaction with a second alkyne to afford allenes (VIII)/(IX) and (X)/(XI) in a one-pot mode. — (ZENG, X.; FREY, G.
