合成了2个N-杂环卡宾钌配合物[RuCl2(L1)(CO)](1),L1=(2,6-二(甲基咪唑-2-鎓盐)吡啶)和[RuCl2(L2)(CO)](2),L2=(2,6-二(正丁基-2-鎓盐)吡啶),并通过元素分析、红外光谱、核磁共振氢谱和核磁共振碳谱对它们的结构进行了表征,X-射线单晶衍射测定了配合物2的分子结构,结果表明配合物2属单斜晶系,C2/c空间群,a=1.814 8(4)nm,b=1.129 2(3)nm,c=1.119 6(2)nm,β=108.862(3)°,且中心Ru(Ⅱ)离子是六配位,同时研究了配合物1和2在Suzuki-Miyaura偶联反应中的催化性质。 Two N-heterocyclic carbene ruthenium complexes [RuCl2 (L1) (CO)] (1) and L1 = (2,6-bis (methylimidazolium) (CO)] (2), L2 = (2,6-di (n-butyl) -2-pyridinium chloride) and their The crystal structure of complex 2 was characterized by X-ray single crystal diffraction. The results show that the complex 2 belongs to the monoclinic space group C2 = c, a = 1.814 8 (4) nm and b = 1.129 2 (3) nm, c = 1.119 6 (2) nm, β = 108.862 (3) °, and the central Ru (Ⅱ) ions are hexacoordinated. At the same time, the complexes 1 and 2 were studied in the Suzuki-Miyaura coupling reaction The catalytic properties.
