Abstract

The reaction of 2,2-dimethylpropylidynephosphine with the cluster [Os3(CO)103121-C2Me)] 1 results in P–C bond cleavage and an insertion of the precoordinated but-2-yne ligand into the phosphorus carbon triple bond of the incoming phosphaalkyne with formation of a novel bridging C3P-moiety in the structurally characterised complex [Os3(CO)82-PCBut){µ3-PC(Me)C(Me)C(But)}] 2, together with a second µ222-ligated phosphaalkyne.
