Novel examples of P-C bond activation under mild conditions are reported.The reactions of phosphinoalkynes Ph2PC<*>CR (R= Ph, Bu^t, Prⁱ) with the formally 46-electron cluster HRu3(CO)9(μ-PPh2) result in P-C bond cleavage, transfer of a phosphido group onto the cluster, and transfer of hydride to the acetylide.The new species Ru3(CO)7(μ-PPh2)2(μ₃-η²-HC<*>CR), of wich the derivative with R = Ph has been studied by X-ray diffraction, are representatives of a new class of μ₃-η²-<*>acetylene clusters with NIDO 5-vertex structures.
