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