Abstract

The reaction of 2,2-dimethylpropylidynephosphine with the cluster [Os3(CO)10(µ3-η1:η2:η1-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)8(µ2-PCBut){µ3-PC(Me)C(Me)C(But)}] 2, together with a second µ2-η2,η2-ligated phosphaalkyne.
