The CuI complex (IPr)Cu(NHPh) IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene} reacts with aryl iodides to form diaryl amine products and (IPr)Cu(I), which was confirmed by independent synthesis and characterization. For the reaction with iodobenzene, the products are diphenylamine and aniline. Protection of the hydrogen para to the iodo functionality with ortho-methyl groups results in quantitative
Cu I络合物(IPr)Cu(NHPh)IPr = 1,3-双(2,6-二异丙基苯基)咪唑-2-亚烷基}与芳基碘化物反应形成二芳基胺产物和(IPr)Cu(I),独立的合成和表征证实了这一点。为了与碘苯反应,产物是二苯胺和苯胺。用邻甲基将对氢对碘官能团的保护导致定量转化为二芳基胺。结合计算和实验研究表明,CN键的形成最有可能是通过氧化加成/还原消除序列发生的。
