  Synthesis of Ru(II) complexes of the new 1-[(P-diphenyl)-2-phosphinoethyl]-3,5-dimethylpyrazole ligand and study of their reactivity toward terminal alkynes

  摘要：

  The reaction between [RuCl2(PPh3)(3)] and one or two equivalent amounts of 1-[(P-diphenyl)-2-phosphinoethyl]-3,5-dimethylpyrazole (1) in dichloromethane gave [RuCl2(PPh3)(1)] (2) or [RuCl2(1)(2)] (3), respectively, in good yields. Activation of propargylic alcohol derivatives by 3 in refluxing dichloromethane and in the presence of NaBPh4 lead to the new allenylidene ruthenium complexes [RuCl(1)(2)(C=C=CPhCH3)][BPh4] ([4][BPh4]) and [RuCl(1)(2)(C=C=CPh2)][BPh4] ([5][BPh4]). The reaction between 3 and phenylacetylene in dichloromethane and in the presence of KPF6 affords the vinylidene complex [RuCl(1)(2)(C-CHPh)][PF6] ([6][PF6]). The X-ray diffraction studies of 2, 3, and [5][BPh4] are reported. (C) 2002 Elsevier Science B.V. All rights reserved.

  Two new N-pyrazole, P-phosphine hybrids ligands: 1-[2-(diphenylphosphanyl)methyl1-3,5-dimethyl pyrazole (LP1) and 1-[2-(diphenylphosphanyl)propyl1-3,5-dimethylpyrazole (LP3) are presented. The reaction of these two ligands and two other ligands reported in the literature: 1-[2-(diphenylphosphanyl)ethyl1-3,5-dimethylpyrazole (LP2) and 1-[2-(diphenylphosphanyl)ethyl1-3,5-diphenylpyrazole (LP4) with [PdCl2(CH3CN)21 yield [PdCl2(LP)] (LP = LP1 (1), LP2 (2), LP3 (3) and LP4 (4)) complexes. All complexes are fully characterised by analytical and spectroscopic methods and the resolution of the crystal structure of complexes 2 and 3 by single crystal X-ray diffraction is also presented. In these complexes the ligands are coordinated to Pd(II) via kappa(2)(N,P) forming metallocycles of six (2) and seven (3) members and finish their coordination with two cis-chlorine atoms. Finally, complex 2 is studied in the palladium-catalysed C-C coupling reaction, being active even for aryl chlorides substrates. (C) 2015 Elsevier BY. All rights reserved.

  The reactivity of (3,5-dimethyl-1H-pyrazol-1-yl)ethyldiphenylphosphine (L) hybrid ligand against Cu(I), Ag(I) and Au(I) has been assayed and compounds [Cu(L)(2)](PF6) (1), [Ag(L)](2)(PF6)(2)center dot 2C(2)H(4)Cl(2)center dot 2C(4)H(10)O (2) and [AuCl(L)](2) (3) have been isolated and fully characterised. A fully characterisation by analytical and spectroscopic methods of 1-3 are presented and X-ray crystal structures of 1 and 2 are also reported. The similar data obtained between 2 and 3 permits to do a serious purpose of the structure of 3 in solid and solution. (C) 2011 Elsevier B. V. All rights reserved.
