Reaction of [WI2(CO)(NCMe)(η2-RC2R)2] (R = Me or Ph) in CH2Cl2 at room temperature with an equimolar quantity of R′N: CHCH: NR′ (R′ = Cy, iPr, Ph, p-MePh or p-MeOPh) gave high yields of the new cationic bisalkyne complexes [WI(CO)(R′N: CHCH: NR′)(η2-RC2R)2]I via successive displacement of acetonitrile and an iodide ligand. The cationic compounds [WI(CO)(CyN: CHCH: NCy)(η2-RC2R)2][BPh4] were also prepared by reaction of [WI2(CO)(NCMe)(η2-RC2R)2] with CyN: CHCH: NCy in the presence of Na[BPh4] in order to confirm the ionic nature of these complexes. 13C NMR spectroscopy indicated that the two alkyne ligands are donating a total of six electrons to the metal in these complexes.
