Abstract

Treatment of Ru( - CHPh)Cl₂(PCy₃)₂ (Cy = cyclohexyl) with K[N(i-Pr₂PS)₂] afforded a mixture of Ru( - CHPh)[N(i-Pr₂PS)₂](PCy₃)Cl (1) and Ru( - CHPh)[N(i-Pr₂PS)₂]₂ (2). Reaction of 1 with TlOPh gave Ru( - CHPh)[N(i-Pr₂PS)₂](PCy₃)(OPh) (3), whereas that with NaOMe yielded the Ru(II) hydride compound Ru(H)[N(i-Pr₂PS)₂][PCy₂(η²- C₆H₉)] (4), in which the dicyclohexyl(cyclohex-3-enyl) phosphine ligand binds to Ru via the phosphorus atom and the C - C bond of the cyclohex-3-enyl ring. The structures of complexes 3 and 4 have been established by X-ray crystallography.
