The reaction of a terminal alkyne (RCCH) and 2-aminopyridine (R′C5NH3NH2) with the dinuclear species [Cp*IrCl2]2 afforded the cationic aminocarbene derivatives Cp*Ir­(Cl)­[ C­(CH2R)­NHC5NH3R′] via a hydroamination and a ligand substitution. The reaction pathway has been examined through computational studies.
