An air-stable dimeric Ru-S complex with an NHC as ancillary ligand for cooperative Si-H bond activation

Résumé

The preparation of a coordinatively unsaturated NHC ruthenium complex with a tethered 2,6-dimesitylphenyl thiolate is described. Unlike related mononudear phosphine complexes, the NHC complex forms an air-stable dimer with bridging sulfur ligands in both the solid state and solution. The dinuclear complex is a precatalyst and activates Si H bonds upon heat-or donor-assisted dissociation into the catalytically active monomer. Its usefulness is illustrated with representative dehydrogenative Si X coupling and hydrosilylation reactions.
