Orthometalated Amino-Carbene Derivatives of Iridium via Anilines and Terminal Alkynes

Abstract

The reaction of a terminal alkyne (RCCH) and an aniline (R′C6H4NH2) with the dinuclear species [Cp*IrCl2]2 afforded cyclometalated amino-carbene derivatives Cp*Ir(Cl)[C(CH2R)NHC6H3R′] via a hydroamination and an orthometalation. The reaction pathway has been examined through deuterium labeling and computational studies
