在室温、有关配体存在下,利用金属铜粉和过氧化苯甲酰的氧化加成配位反应合成了四种铜(Ⅱ)配合物(配体分别为联吡啶、双二苯基膦乙烷、2-氨基吡啶、苯并咪唑)。同时又利用双齿有机膦配体(dppm=双二苯基膦甲烷,dppe=双二苯基膦乙烷,dppp=双二苯基膦丙烷,dppb=双二苯基膦丁烷)和金属铜盐的还原取代反应合成了四种一价铜(Ⅱ)配合物。通过元素分析确定了配合物的组成,经X射线四圆单晶衍射确定了配合物的分子结构,配合物的晶体结构由直接法和Fourier合成方法解出。利用电子光谱等手段研究了氧化加成配位和还原取代配位反应的机理。初步建立了一套简单有效的合成铜(Ⅰ,Ⅱ)配合物的新方法。

Four copper (Ⅱ) complexes were synthesized at room temperature by oxidative addition reaction of metallic copper powder and dibenzoyl peroxide in the presence of ligands (2,2'-bipy, dppe, 2-aminopyridine and benzoimidazole, respectively). Four copper (Ⅰ) complexes were synthesized by reduction substitution reaciton of copper (Ⅱ) salts with different diphosphine ligands [Ph~2P(CH~2)~nPPh~2, dppm (n=1), dppe (n=2), dppp (n=3) and dppb (n=4)]. The complexes were characterized by elemental analysis and single crystal X-ray analysis. The reaction mechanism was discussed on the basis of electronic spectra. A facile synthetic method of copper (Ⅰ, Ⅱ) complexes was provided.
