  Preparation of [Ru(η⁶-C₆Me₆)Cl(CCPh)(RNC)](R = C₈H₉or C₆H₂Me₃-2,4,6) and its reaction with tetracyanoethylene. Crystal structures of [Ru(η⁶-C₆Me₆)Cl{C[C(CN)₂]CPhC(CN)₂}(C₈H₉NC)] and cis-[RuCl₂(C₈H₉NC)₂]

  摘要：

  Reaction of [Ru(eta(6)-C(6)Me(6))Cl-2(RNC)] with phenylacetylene in the presence of potassium hydroxide in methanol gave the corresponding acetylide complex [Ru(eta(6)-C(6)Me(6))Cl(C=CPh)(RNC)] (R = C8H9 1a or 2,4,6-Me(3)C(6)H(2) 1b). Compound la reacted with triphenylphosphine at reflux in toluene to give [RU(eta(6)-C(6)Me(6))Cl(C=CPh)(PPh(3))] 2 and [RUCl(C=CPh)(C8H9NC)(PPh(3))] 3. When 1a was treated with tetracyanoethylene (tcne) at room temperature [Ru(eta(6)-C(6)Me(6))Cl{C[=C(CN)(2)]CPh=C(CN)(2)}(C8H9NC)] 4 was obtained. The structure was confirmed by an X-ray analysis: space group Pbca, a = 20.128(4), b = 17.821(6), c = 17.407(9) Angstrom, and Z = 8. The molecule contains a ligand resulting from alpha,beta addition. of C(CN)(2) fragments to the acetylide group. Reaction of 2 with tcne gave [RU(eta(6)-C(6)Me(6))Cl{C(CN)(2)CPhC=C(CN)(2)}] 5 which has lost the terminal isocyanide in 4. Preparation and X-ray analysis of square-planar cis-[RuCl2(C8H9NC)(2)] were also carried out: space group P ($) over bar 1, a = 10.573(3), b = 10.865(3), c = 8.244(2) Angstrom, alpha = 99.66(2), beta = 93.37(2). gamma = 85.85(3)degrees and Z = 2. The structure consists of a pair of molcules of cis configuration with a centrosymmetry, but there is no interaction between the ruthenium atoms.

  摘要：

  Reactions of [(p-cymene)RuCl2](2) (1a) with dpmp ((Ph2PCH2)(2)PPh) in the absence or presence of KPF6 afforded the ionic complexes [{(p-cymene)RuCl2}(dpmp-P-1,P-3,P-2){RuCl(p-cymene)}](X) (2a,: X=Cl; 2a(2): X=PF6). A (p-cymene)RuCl moiety constructs a 6-membered ring coordinated by two terminal P atoms of the dpmp ligand and another one binds to a central P atom of the ligand. Reactions of [(C6Me6)RuC](2)](2) (1b) with an excess of dpmp in the presence of KPF6 gave a 4-membered complex [(C6Me6)RuCl(dpmp-P-1, P-2)](PF6) (3b), chelated by a terminal and a central P atom and another terminal atom is free. Use of Ag(OTf) instead of KPF6 gave [{(C6Me6)RuCl2(dpmp)Ag}(2)](OTf)(2) (5b) that the Ag atoms were coordinated by a terminal and a central P atom of each dpmp ligand. Reaction with an equivalent of dpmp in the presence of KPF6 gave [{(C6Me6)RuCl}(dpmp-P-1,P-2,P-3){(C6Me6)RuCl2}](PF6) 4b. Complex has a structure that the (C6Me6)RuCl2 moiety coordinated to the free P atom of 3b. Complex 3b was treated with MCl2(cod) (M=Pd, Pt), [Pd(MesNC)(4)](PF6)(2) (MesNC=2,4,6-Me3C6H2NC) or [Pt-2(XylNC)(6)](PF6)(2) (XylNC=2,6-Me2C6H3NC), generating [{(C6Me6)RuC](dpmp)}(2)MCl2](PF6)(2) (8b: M=Pd; 9b: M=Pt), [{(C6Me6)RuCl(dpmp)}(2){Pt(MesNC)(2)}](PF6)(4) (10b) and [{(C6Me6)RuCl(dpmp)}(2){Pt-2(XylNC)(4)}](PF6)(4) (11b), respectively. Complex 3b reacted readily with [Cp*MCl2](2) (M=Rh, Ir) or AuCl(SC4H8), affording the corresponding hetero-binuclear complexes [{(C6Me6)RuCl}(dpmp-P-1,P-2;P-3)(MCl2Cp*](PF6) (6b: M = Rh; 7b: M = Ir) and [{(C6Me6)RuCl}(dpmp-P-1, P-2, P-3)(AuCl)](PF6) (12b). These complexes have two chiral centers. Some complexes were separated as two diastereomers by successive recrystallization. The structures of 3b, 5b, 6b, 8b and 12b were confirmed by X-ray analyses.
