Abstract: Reaction of (PCP)Ru(CO)(CI) (1) with NaBAr'4 yields the bimetallic product [{(PCP)Ru(CO)}2 (μ-CI)][BAr'4] (2). The monomeric five-coordinate complexes [(PCP)Ru(CO)(ɳ1-CICH2CI)][BAr'4] (3) and [(PCP)Ru(CO)(ɳ1-N2)][BAr'4] (4) are synthesized upon reaction of (PCP)Ru(CO)(OTf) (6) with NaBAr'4 in CH2CI2 or C6H5F, respectively. The solid-state structures of 2,3, and 4 have been determined by X-ray diffraction studies of single crystals. The reaction of 3 with PhCHN2 or PhC=CH affords carbon-carbon coupling products involving the aryl group of the PCP ligand in transformations that likely proceed via the formation of Ru carbene or vinylidene intermediates. Density functional theory and hybrid quantum mechanics/molecular mechanics calculations were performed to investigate the bonding of weak bases to the 14-electron fragment [(PCP)Ru(CO)]+ and the energetics of different isomers of the product carbene and vinylidene complexes.
