be obtained by the one pot reaction involving ligand 1, [Cu(CH3CN)4]PF6 and triphenylphosphine. Solid state structures of all the five compounds were established by single crystal X-ray diffraction analysis. The solid state structures of the copper complexes 3–5 reveal a distorted tetrahedral geometry around the copper (I) centers. The copper complexes 3–5 were tested as catalysts for the coupling
摘要 我们报告了两种基于乙二醛的配体 N,N 双(二苯甲基)-1,4-二氮杂-1,3-丁二烯配体 (DADPh2, 1) 和更庞大的 N,N 双(三苯甲基)-1 的完整表征, 4-二氮杂-1,3-丁二烯配体 (DADPh3, 2) 分别由乙二醛与二苯基甲胺和三苯基甲胺的缩合反应生成。[Cu(DADPh2)2]PF6(3)具有两个中性双齿N,N双(二苯基-甲基)-1,4-二氮杂-1,3-丁二烯配体的铜(I)配合物是通过反应制备的[Cu(CH3CN)4]PF6 和 1 在二氯甲烷中的比例为 1:2。在与 N,N 双(三苯甲基)-1,4-二氮杂-1,3-丁二烯配体 (2) 和 [Cu(CH3CN)4]PF6 在二氯甲烷中的类似反应中,产生相应的杂配铜 (I) 配合物 [Cu( DADPh3)(CH3CN)2]PF6 (4)。另一种铜 (I) 配合物 [Cu(DADPh2)(PPh3)]PF6 (5)
