Ruthenium(II) and ruthenium(IV) complexes containing κ1-P-, κ2-P,O-, and κ3-P,N,O-iminophosphorane-phosphine ligands Ph2PCH2P{=NP(=O)(OR)2}Ph2 (R = Et, Ph): Synthesis, reactivity, theoretical studies, and catalytic activity in transfer hydrogenation of cyclohexanone

[{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.

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.

Base-assisted cyclometalation and phosphorus-carbon bond cleavage in (arene)ruthenium(ii) complexes containing functionalized iminophosphorane- phosphine ligands Ph2PCH2P{=NP(=X)(OR)2}PH 2 (X = O, S; R = Et, Ph)

The bond-assisted cyclometalation and phosphorus-carbon bond cleavage in (Arene)ruthenium(II) complexes are discussed. The complexes contain functionalized iminophosphorane-phosphine ligands Ph2PCH 2P{=NP(=X)(OR)2}Ph2 (X = O, S; R = Et, Ph). It is found that the functionalized iminophosphorane-phosphines act as versatile ligands upon coordination to a (η6-arene)-ruthenium(II) fragment. The results show that the ligands are used as templates for the construction and stabilization of unusual organometallic ruthenium(II) complexes.
