The reaction of [Cp*RhCl2]2 with an aniline (R′NH2) and a terminal alkyne (RCCH) afforded the N-containing cyclometalated rhodium complexes Cp*Rh­(Cl)­[N­(R′)C­(CH2R)­CHCR] via a hydroamination and a 1,2-insertion of an alkyne. A reaction pathway has been proposed on the basis of deuterium labeling experiments and computational studies.
