(Z)-Selective cross-dimerization of arylacetylenes with silylacetylenes catalyzed by vinylideneruthenium complexes

Hiroyuki Katayama, Hiroshi Yari, Masaki Tanaka and Fumiyuki Ozawa

The vinylideneruthenium(II) complexes bearing bulky and basic tertiary phosphine ligands, RuCl2(CCHPh)L2(L = PPri3, PCy3), serve as good catalyst precursors for (Z)-selective cross-dimerization between arylacetylenes and silylacetylenes in the presence of N-methylpyrrolidine.
