Abstract

The synthesis and characterization of a cyclometalated ruthenium(II) complex [RuCl(PSiP^Cy)] containing monoanionic, tridentate coordinating PSiP-pincer ligand [κ³-(2-Cy₂PC ₆H₄)₂SiMe]^- ([PSiP^Cy]) are reported. Complex 3 is one of the few examples of halogenated ruthenium(II) complexes supported by the pincer-like bis(phosphino)silyl ligand. The structure of complex 3 was unambiguously determined by multinuclear NMR and single crystal X-ray analysis. This compound has also been shown to catalyze the transfer hydrogenation of ketones to the corresponding secondary alcohols efficiently with 2-propanol as the hydrogen source instead of using molecular dihydrogen gas or hazardous reducing agents (e.g., NaBH₄ and LiAlH₄), and ^tBuOK as the base.
