Abstract

The diyne complex [Cp*Ir(CO)(η²-ArC≡CC≡CAr)] reacts with two-electron donor ligands to form the iridacyclobutenone [Cp*Ir(L){C(C≡CAr)=C(Ar)C=O}]. Kinetic measurements and computational studies support the proposal that the reaction pathway involves alkyne insertion followed by coordination of the two-electron donor ligand.
