Cadierno V, Diez J, Garcia-Alvarez J, Gimeno J, Rubio-Garcia J: Novel ruthenium (ii) complexes containing the N-phosphorylated iminophosphorane-phosphine ligand Ph (2) PCH (2) P{[double bond, length as m-dash] NP ([double bond, length as m-dash] O)(OEt)(2)}Ph (2): a new coordination mode of its methanide anion. Dalton Trans. 2008 Nov 14;(42):5737-48. Epub 2008 Sep 2.
The reactivity of complex [Ru (eta (6)-p-cymene)(kappa (3) P,N,O-Ph (2) PCH (2) P{[double bond, length as m-dash] NP ([double bond, length as m-dash] O)(OEt)(2)}Ph (2))][SbF (6)](2) towards a variety of mono- and bidentate neutral ligands has been studied, allowing the high-yield synthesis of the novel half-sandwich Ru (ii) derivatives [Ru (eta (6)-p-cymene)(L)(kappa (2) P,O-Ph (2) PCH (2) P{[double bond, length as m-dash] NP ([double bond, length as m-dash] O)(OEt)(2)}Ph (2))][SbF (6)](2) (L = N [triple bond, length as m-dash] CMe , N [triple bond, length as m-dash] CEt , PMe (3), PMe (2) Ph , PMePh (2), PPh (3), P (OMe)(3), P (OEt)(3), P (OPh)(3), py , kappa (1) P-dppm , kappa (1) P-dppe ), as well as the octahedral species [Ru (Ninsertion markN)(2)(kappa (2) P,O-Ph (2) PCH (2) P{[double bond, length as m-dash] NP ([double bond, length as m-dash] O)(OEt)(2)}Ph (2))][SbF (6)](2) (Ninsertion markN = bipy , phen ). Deprotonation of complexes ,, upon treatment with an excess of NaOH in CH (2) Cl (2), generates the monocationic derivatives [Ru (Ninsertion markN)(2)(kappa (2) P,N-Ph (2) PC (H)[double bond, length as m-dash] P{NP ([double bond, length as m-dash] O)(OEt)(2)}Ph (2))][Cl] (Ninsertion markN = bipy , phen ) in which the methanide anion adopts an unprecedented kappa (2) P,N bidentate coordination mode. The structures of compounds , and have been determined by single-crystal X-ray diffraction methods. |
