Activation of alkynes with [Cp*MCl2]2 (M=Rh or Ir) towards hydroamination reactions

Activation of alkynes with [Cp*MCl2]2 (M=Rh or Ir) towards hydroamination reactions

Abstract Activation of alkynes for hydroamination reactions have been studied with the iridium and rhodium dimeric complexes [Cp*MCl2]2 (M=Rh or Ir). The reaction of [Cp*IrCl2]2, 1a with terminal alkynes and anilines afforded a variety of iridium amino-carbenes, whereas the rhodium analogue 1b gave...
