tetramethylethylene. For cis-cyclooctene, indene, methyl acrylate, methyl methacrylate, vinyl methyl ketone, tert-butylethylene, and neopentylethylene, as well as for 1-hexene and cyclopentene, yields of corresponding aziridines vary from 44% to 83%. The catalytic activity and efficiency of the reported copper complexes decrease moderately in the absence of NaBArF4.
衍生自二(2-吡啶基)甲烷或吡啶本身的四配位二氯铜(II)配合物在弱配位氯仿中,在存在1-2当量的NaBAr F 4(BAr F 4 - =四[3,5-二(三氟甲基)苯基]硼酸盐)。对于诸如苯乙烯,三和四甲基乙烯这样的反应性烯烃,以1:1的烯烃/ PhINTs比和1-5摩尔%的催化剂负载量,可以获得超过90%的高氮丙啶收率。用于顺式环辛烯,茚,丙烯酸甲酯,甲基丙烯酸甲酯,乙烯基甲基酮,叔丁基丁基乙烯和新戊基乙烯,以及1-己烯和环戊烯的相应氮丙啶的收率从44%到83%不等。在没有NaBAr F 4的情况下,所报道的铜配合物的催化活性和效率适度降低。
