Abstract

Reactions of 2-vinylpyridine with the triruthenium complexes [Ru₃(CO)₁₂] and [Ru₃(CO)₁₀(μ-dppm)] leads to a previously unknown double carbon−hydrogen bond activation of the β-carbon of the vinyl group to afford the pentaruthenium and triruthenium complexes [Ru₅(CO)₁₄(μ₄-C₅H₄CH═C)(μ-H)₂] (1) and [Ru₃Cl(CO)₅(μ-CO)(μ-dppm)(μ₃-NC₅H₄CH═C)(μ-H)] (2), respectively. Crystal structures reveal two different forms of bridging of the dimetalated 2-vinylpyridyl ligand, capping a square face in 1 and a triangular face in 2.
