Résumé

[{Ru(η6-p-cymene)(μ-Cl)Cl}2] and [{Ru(η3:η3-C10H16) (μ-Cl)Cl}2] react with Ph2PCH2P{=NP(=O)(OR)2}Ph2 (R = Et (1a), Ph (1b)) affording complexes [Ru(η-p-cymene)Cl2Cl2(κ1-P- Ph2PCH2P{=NP(=O)(OR)2}Ph2)] (R = Et (2a), Ph (2b)) and [Ru(η3:η3-C10H16) Cl2(κ1-P-Ph2PCH2P{=NP(=O) (OR)2}Ph2)] (R = Et (6a), Ph (6b)). While treatment of 2a with 1 equiv of AgSbF6 yields a mixture of [Ru(η6-p-cymene)Cl(κ2-P, O-Ph2PCH2P{=NP(=O)(OEt)2}Ph2)]- [SbF6] (3a) and [Ru(η6-p-cymene)Cl(κ2-P,N-Ph2 PCH2P{=NP(=O)(OEt)2}Ph2)][SbF6] (4a), [Ru(η6-p-cymene)Cl(κ2. P,O-Ph2PCH2P{=NP(=O)(OPh)2} Ph2)][SbF6] (3b) and [Ru(η3:η3-C10H16)Cl (κ2-P,O-Ph2PCH2P{=NP(=O) (OR)2}-Ph2)][SbF6] (R = Et (7a), Ph (7b)) are selectively formed from 2b and 6a,b. Complexes [Ru(η6-p-cymene)(κ3-P,N,O-Ph2 PCH2P{=NP(=O)(OR)2}Ph2)] [SbF6]2 (R = Et (5a), Ph (5b)) and [Ru(η3:η3-C10H16) (κ3-P,N,O-Ph2PCH2P{= NP(=O)(OR)2}Ph2)][SbF6]2 (R = Et (8a), Ph (8b)) have been prepared using 2 equiv of AgSbF6. The reactivity of 3-5a,b has been explored allowing the synthesis of [Ru(η6-p-cymene)X2(κ1-P- Ph2PCH2P{=NP(=O)(OR)2}Ph2)] (R = Et, Ph; X = Br, I, N3, NCO (9-12a,b)). The catalytic activity of 2-8a,b in transfer hydrogenation of cyclohexanone, as well as theoretical calculations on the models [Ru(η6-C6H6)Cl(κ2-P, N-H2PCH2P{=NP(=O)-(OH)2} H2)]+ and [Ru(η6-C6H6)Cl(κ2-P, O-H2PCH2P{=NP(=O)(OH)2} H2)]+, has been also studied.
