Abstract: Reaction of [Ir4H(CO)10 (μ-PPh2)] with BuLi, Ph2PC≡CPh and then Mel gives [Ir4 (CH 3)(CO)8 (μ4-η3-Ph 2PCCPh)(μ-PPh2)], which undergoes a reversible two-step CO insertion under extremely mild conditions to yield Ir4{(CH 3C(O)}(CO)8-(μ4:η3-Ph 2PCCPh)(μ-PPh2)] as the final product; the structures of both species have been established by X-ray diffraction studies.
