The promoter effect of anionic nucleophiles on reactions of metal carbonyl complexes is of high current interest. In particular, several novel catalytic processes of potential industrial relevance are based on Ru{sub 3}(CO){sub 12}/halide systems as catalyst precursors. The authors have found that the activated complex (PPN)(Ru{sub 3}({mu}-Cl)(CO){sub 10}) ((PPN)(3)), which is readily obtained from the initial halide adduct (PPN)(Ru{sub 3}({eta}{sup 1}-Cl)(CO){sub 11}) ((PPN)(2)) (PPN = bis(triphenylphosphine)iminium), reacts with alkynes at 25{degree}C in THF (reaction 1) to produce a labile species (PPN)(Ru{sub 3}({mu}-Cl)({mu}-{eta}{sup 2}-RCCR{prime})(CO){sub 9}) ((PPN)(4)) that serves as a convenient precursor to new and known alkyne-substituted derivatives of Ru{sub 3}(CO){sub 12}.
