Abstract

Ruthenium(II) complexes containing both σ-alkenyl and η2-carboxylate ligands Ru(O2CR2)(CHCHR1)(CO)(PPh3) 2 (R1=tBu, Ph; R2=CH=CHCH=CHCH3) react with phenylacetylene in two stages. Their reaction with an equivalent amount of the alkyne led to the formation of a σ-alkynyl-containing ruthenium(II) complex Ru(O2CR2)(CCPh)(CO)(PPh3)2 (R2=CH=CHCH=CHCH3), the molecular structure of which was established by X-ray diffraction. This σ-alkynyl complex then reacts with phenylacetylene to form a σ-butenynyl-containing compound Ru(O2CR2)(C(CCPh)=CPhH)(CO)(PPh3)2 (R2=CH=CHCH=CHCH3). Both reactions support the key role of alkynyl ligands in the dimerization of alkynes.
