Summary
Phenylacetylene reacts stoichiometrically or in excess with the Ru—H bond of RuH(CO)(PPh3)2(L) (LH = 2-hydroxypyridine, 2-hydroxy-6-methylpyridine, acetylacetone, benzoylacetone, 2-hydroxyacetophenone, 2-hydroxypropiophenone, 2-hydroxybenzophenone and 4-methoxy-2-hydroxybenzophenone) in boiling benzene to give σ-vinylic or σ-vinylalkynyl complexes of the type Ru(CO)-(PPh3)2(L)(CH\( = \)CHPh) and Ru(CO)(PPh3)2(L){C-(C\( \equiv \)CPh)\( = \)CHPh} in good yield. The vinylic complex can also be obtained by reacting the sodio derivative of the chelating ligand with the 16e− unsaturated complex, [Ru(CO)Cl(CH\( = \)CHPh)(PPh3)2], in CH2Cl2/MeOH mixture at ambient temperature. These complexes have been characterized by elemental analyses, and i.r., 1H, 13C and 31P n.m.r. spectroscopy.
