Synthesis and properties of hydrotris(pyrazolyl)borate (Tp) ruthenium complexes with benzophenone imine: X-ray crystal structure of [TpRu(HN=CPh2)(PEt3)2][BPh4]
摘要:
The complexes [TpRuCl(dippe)] (dippe = 1,2-bis(diisopropylphosphino)ethane) and [TpRuCl(PEt3)(2)] react with HN=CPh2 and NaBPh4 in MeOH affording the cationic mononuclear imine derivatives [TpRu(HN=CPh2)(dippe)][BPh4] and [TpRu(HN=CPh2)(PEt3)(2)][BPh4], respectively. The X-ray crystal structure of the latter has been determined. The reaction of [TpRuCl(PMePr2)((MeCN)-C-i)] with HN=CPh2 led to the neutral imine derivative [TpRuCl((PMePr2)-Pr-i)(HN=CPh2)], which adds a second imine ligand upon chloride dissociation affording the cationic bis(imine) complex [TpRu((PMePr2)-Pr-i)(HN=CPh2)(2)](+). The cationic complexes [TpRu(HN=CPh2)(dippe)][BPh4] and [TpRu(HN=CPh2)(PE3)(2)][BPh4] react with KOBut in tetrahydrofuran yielding the neutral metalated species [TpRu(sigma-eta(1)-C6H4C(Ph)=NH)(dippe)] and the phenyl complex [TpRu(sigma-eta(1)-C6H5)(PEt3)(2)], respectively. All compounds were characterized by IR, NMR and microanalysis. (C) 2000 Elsevier Science S.A. All rights reserved.
