Structure and catalytic activity of the ruthenium(I) sawhorse-type complex [Ru₂{μ,η²-CF₃(CF₂)₅COO}₂(DMSO)₂(CO)₄]

Abstract

The title compound, cis-di-μ-perfluoroheptanoato-κ(4)O:O'-bis[dicarbonyl(dimethyl sulfoxide-κS)ruthenium(I)](Ru-Ru), [Ru2(C7F13O2)2(C2H6OS)2(CO)4], is a sawhorse-type dinuclear ruthenium complex with two bridging perfluoroheptanoate ligands, and with two dimethyl sulfoxide (DMSO) ligands in the axial positions coordinating via the S atoms. It is a new example of a compound with an aliphatic fluorinated carboxylate ligand. The Ru-Ru bond distance of 2.6908 (3) Å indicates a direct Ru-Ru interaction. The compound is an active catalyst in transvinylation of propionic acid with vinyl acetate.
