Enhanced reactivity is shown by uncoordinated C≡C bonds in the proximity of a metal in phosphanylacetylene complexes. cis ‐[Pt(C 6 F 5 ) 2 (thf) 2 ] reacts with [M(C 6 F 5 ) 2 (PPh 2 C≡CPh) 2 ] (M=Pt, Pd) to form binuclear complexes containing the novel 2,3‐bis(diphenylphosphanyl)‐1,3‐butadien‐1‐yl bridging ligand. Substitution of the solvent ligands with, for example, PPh 2 H (see picture) provides species that could be characterized by X‐ray crystallography.
