Carbon–carbon bond formation by alkyne–µ,η2-acetylide and alkyne–CO coupling in the reaction of (OC)5MCCPH (M = MN, Re) with HOs3(CO)10(µ,η2-CCPh). X-Ray structure of HOs3Re(CO)14(C2Ph)2

Abstract

Addition of (OC)₅MCCPh (M = Mn,Re) to HOs₃(CO)₁₀(µ,η²-CCPh) leads to the formation of carbon–carbon bonds under mild conditions to yield metal cluster compounds HOs₃M(CO)₁₄(C₂Ph)₂; the cluster HOs₃Re(CO)₁₄(C₂Ph) has been characterized by an X-ray structure analysis.
