  名称：

  Base-Assisted Cyclometalation and Phosphorus−Carbon Bond Cleavage in (Arene)ruthenium(II) Complexes Containing Functionalized Iminophosphorane-Phosphine Ligands Ph₂PCH₂P{NP(X)(OR)₂}Ph₂ (X = O, S; R = Et, Ph)

  摘要：

  Complexes [RuCl(eta(6)-p-cymene)(kappa(2)-P,X-Ph2PCH2P{=NP(=X)(OR)(2)}Ph-2)][SbF6] (X = O, R = Et (1a), Ph (1b); X = S, R = Et (2a), Ph (2b)) react with a stoichiometric amount of NaH, in THF at rt, to generate the neutral cyclometalated compounds [RuCl(kappa(2)-P,C-Ph2PCHP-{=NP(=X)(OR)(2)}Ph-2)( eta(6)-p-cymene)] (X = O, R = Et (3a), Ph (3b); X = S, R = Et (4a), Ph (4b)), via selective deprotonation of the methylenic backbone of the coordinated iminophosphorane-phosphine ligands. Treatment of 3-4a,b with AgSbF6, in CH2Cl2 at rt, affords the corresponding cationic species [Ru(kappa(3)-P,C,X-Ph2PCHP{=NP(=X)(OR)(2)}Ph-2)(eta(6)-p-cymene)]-[SbF6] (X = O, R = Et (7a), Ph (7b); X = S, R = Et (8a), Ph (8b)) through the intramolecular O- or S-coordination of the free -Ph2P=NP(=X)(OR)(2) fragment. Complexes 7-8a,b can also be prepared by reaction of the dicationic derivatives [Ru(eta(6)-p-cymene)(kappa(3)-P,N,X-Ph2PCH2P-{=NP(=X)(OR)(2)}Ph-2)] [SbF6](2) (5-6a,b) with 1 equiv of NaH. Formation of complexes 3-4a,b and 7-8a,b proceeds, in all cases, in a diastereoselective manner. Phosphorus-carbon bond splitting has been observed upon treatment of complexes 1-2a,b, 3-4a,b, or 7-8a,b with an excess of NaH, in wet THF at rt, affording the novel phosphinito derivatives [Ru(kappa(2)-C,X-CH2P{=NP(=X)(OR)(2)}Ph-2){kappa(1)-P-P(=O)Ph-2}(eta(6) -p-cymene)] (X = O, R = Et (10a); X = S, R = Et (11a), Ph (11b)). Protonation and methylation of 10-11 a,b generates the cationic species [Ru(kappa(2)-C,X-CH2P{=NP(=X)(OR)(2)}Ph-2){kappa(1)-P-P(OH)Ph-2}(eta(6)-p-eymene)] [BF4] (X = O, R = Et (12a); X = S, R = Et (13a), Ph (13b)) and [Ru(kappa(2)-C,X-CH2P{=NP(=X)(OR)(2)}Ph-2){kappa(1)-P-P(OMe)Ph-2}(eta(6)-p-cymene)] [CF3SO3] (X = O, R = Et (14a); X = S, R = Et (15a), Ph (15b)), respectively, via selective electrophilic addition at the Ph2P=O group. The structure of compounds [RuCl(kappa(2)-P,C-Ph2PCHP{=NP(=O)(OPh)(2)}Ph-2)(eta(6)-p-cymene)] (3b) and [Ru(kappa(2)-C,S-CH2P{=NP(=S)(OEt)(2)}Ph-2){kappa(1)-P-P(=O)Ph-2}(eta(6)-C6H6)] (11a') has been determined by X-ray crystallography.
