RhCl3/Amine-catalyzed Cyclotrimerization of Alkynes

RhCl3/Amine-catalyzed Cyclotrimerization of Alkynes

RhCl3/amine was found to be an efficient catalyst for the cyclotrimerization of alkynes. The [2+2+2] cyclotrimerization of internal alkynes proceeded smoothly to afford hexa-substituted benzenes regioselectively in moderate to high yields.
