Abstract

Treatment of [Ru(η⁶-C₆Me₆)Cl ₂]₂ with AgOTf (OTf^- = triflato) followed by K[N(R₂PQ)₂] gave the 16-electron complexes [Ru(η⁶-C₆Me₆){η²-N(R ₂PQ)₂}][OTf] [Q = S, R = Ph (1) or iPr (2); Q = Se, R = Ph (3) or iPr (4)] which were isolated as airstable blue or dark green crystals. For complex 1, when the crude product was recrystallised from CH ₂Cl₂/hexane in air, orange crystals of [Ru(η⁶-C₆Me₆){η³-N(Ph ₂PS)₂}][OTf] (1a) were isolated as a minor product. The reaction of compound 1 with ammonia, hydrazine hydrate and 4,4′-bipyridyl (4,4′-bpy) gave the 18-electron adducts [Ru(η⁶-C ₆Me₆){η²-N(Ph₂PS) ₂}L][OTf] [L = NH₃ (5), N₂H₄ (6)] and dinuclear [{Ru(η⁶-C₆Me₆) [η²-N(Ph₂PS)₂]}₂(μ-4, 4′-bpy)][OTf]₂ (7), respectively. Treatment of compound 2 with Li[BEt₃H] and NaBH₄ afforded the ethyl [Ru(η⁶-C₆Me₆){N(iPr₂PS) ₂}Et] (8) and hydride [Ru(η⁶-C₆Me ₆){η²-N(iPr₂PS)₂}H] (9) compounds, respectively. Formal potentials for Ru[N(R₂PQ) ₂] complexes have been determined. The structures for complexes 1, 1a, 5, 6, 8 and 9 have been established by X-ray crystallography.
