Abstract

When a solution of Cp(Ph₃P)Ru{SiMe₂⋯O-(Me)⋯SiMe₂} (1; Cp = η⁵-C₅H₅) and a two-electron-donating ligand L was heated at 130 °C, a C-H bond of a phenyl group was activated by the Ru=Si double bond, and the complexes CpLRuSiMe₂(o-C₆H₄PPh₂) (2a, L = PPTi₃; 2b, L = PMe₃; 2c, L = PEt₃ 2d, L = P(OMe)₃; 2e, L = ^tBuNC) were obtained. Heating 1 in the absence of a ligand at 130 °C gave CpRuSiMe₂(o-C₆H₄PPh₂)-(H)(SiMe ₂OMe) (3).
