XCu(PP?h_?)_3,(X为卤素、硼氢阴离子等)是一类稳定的亚铜络合物,对一些有机反应和聚合反应有催化作用,曾用于多种成像过程,因而吸引人们对这一类化合物的结构和性质进行了广泛的研究。Lippard等测定了这类化合物在溶液中的表观分子量表明,在溶液中这类化台物的配体可以离解,并与络合物形成动态平衡。本文用 FX-90Q NMR 谱仪研究了四种络合物(PPh_3)_3CuX(X=Cl~-、Br~-、I~-和CN~-)在氯仿溶液中的~(32)PNMR谱及加入不同浓度的PPh_3对其~(35)P
XCu (PP? H_?) _3 (X is halogen, borohydride, etc.) is a class of stable cuprous complexes that catalyze some organic reactions and polymerizations and was used in a variety of imaging processes and thus It has drawn extensive research on the structure and properties of this class of compounds. The apparent molecular weight of such compounds in solution as determined by Lippard et al. Shows that the ligands of such compounds in the solution can dissociate and form a dynamic equilibrium with the complex. In this paper, ~ (32) PNMR spectra of four complexes (PPh_3) _3CuX (X = Cl ~ -, Br ~ -, I ~ - and CN ~ -) in chloroform solution were studied by FX- Different concentrations of PPh_3 on its ~ (35) P
