The Metathesis-Facilitated Synthesis of Terminal Ruthenium Carbide Complexes:  A Unique Carbon Atom Transfer Reaction

Ruthenium benzylidene metathesis catalysts react with 2,3-dicarbomethoxymethylene−cyclopropane, eliminating styrene and dimethyl fumarate, and producing the first terminal ruthenium carbide complexes. The products are diamagnetic, air-stable, and moderately soluble in hydrocarbon solvents. An X-ray...

Description
Summary:Ruthenium benzylidene metathesis catalysts react with 2,3-dicarbomethoxymethylene−cyclopropane, eliminating styrene and dimethyl fumarate, and producing the first terminal ruthenium carbide complexes. The products are diamagnetic, air-stable, and moderately soluble in hydrocarbon solvents. An X-ray study of Ru(⋮C:)Cl2(P(C6H11)3) (1,3-dimesityl-4,5-dihydroimidazol-2-ylidene) shows a Ru−C distance of 1.650(2) Å, consistent with the presence of a very short Ru−C triple bond.
