The synthesis and characterization of base-stabilized and base-free pincer-type bis(phosphine)/silylene [P2Si]Ru complexes are reported. The base-free complex readily reduces CO2 and CS2 via silylene-assisted hydride transfer, affording structurally distinct products with silicon-to-ruthenium formate and dithioformate bridges. Here we present ongoing explorations of small-molecule activation, including isocyanates and isocyanides, to provide further insight into reactivity of pincer-supported silylenes and possibilities for catalysis.
