Synthesis and Reactivity of [PPh₄][Ru(N)Me₃(SSiMe₃)], a Ruthenium(VI) Trimethylsilanethiolate Complex

The anionic organoruthenium complex [PPh₄][Ru(N)Me₃Br] reacts with NaSSiMe₃ to give the trimethylsilanethiolate complex [PPh₄][Ru(N)Me₃SSiMe₃], 1. Reactions of 1 with CsF or with PPh₄Cl in nitromethane or acetonitrile produce [PPh₄][Ru(N)Me₃(SH)], 2. The molecular structure of 2 was determined by X-ray diffraction. Complex 1 reacts with [Os(N)(CH₂SiMe₃)₂(μ-Cl)]₂ to form a heterobimetallic complex, [PPh₄][Me₃(N)Ru(μ-S)Os(N)(CH₂SiMe₃)₂(NCCH₃)], 3.
