Abstract: Reaction of [Hlr4(CO)10(μ-PPh2)] 1 with PPh2C≡CPh yields the CO replacement compound [Hlr 4(CO)9(PPh2C≡CPh)(μ-PPh2)] 3, that is readily converted to the species [Ir4(CO) 7(μ-CO)(μ-PPh2)2(μ3- η2-HC2Ph)] 4; reaction of 1 with PPh 2C≡CPh in the presence of base, followed by protonation, affords the novel compound [Hlr4(CO)9(μ4- η3-PPh2C2Ph)(μ-PPh2)] 5.
