Abstract
The diethyldithiocarbamate hydride ruthenium complex [RuH(kappa(2)-S2CNEt2)(CO)(PPh3)(2)] reacts with excess phenylacetylene to give the alkynyl complex [Ru(C=CPh)(kappa(2)-S2CNEt2)(CO)(PPh3)(2)] via the intermediate alkenyl complex [Ru(CH=CHPh)(kappa(2)-S2CNEt2)(CO)(PPh3)(2)] and with 1,4-diphenylbutadiyne to give the enynyl complex [Ru{eta(1)-C(C=CPh)=CHPh}(kappa(2)-S2CNEt2)(CO)(PPh3)(2)]. The alkenyl complex [Ru(CH=CHPh)(kappa(2)-S2CNEt2)(CO)(PPh3)(2)] is a convenient precursor for alkynyl complexes of the type [Ru(C=CR)(kappa(2)-S2CNEt2)(CO)(PPh3)(2)] (R = aryl, alkyl, C6H4-4-C=CH).
