Mild catalytic dehydrogenation of cycloalkanes (cyclo-C(5)H(10), cyclo-C(6)H(12), cyclo-C(8)H(16)) and aziridination of resulting olefins is reported with PhINTs and copper-[2.1.1]-(2,6)-pyridinophane (L) complexes LCuX(n)(n= 1, 2; X = Cl, OTf)"activated" with NaBAr(F)(4) in dichloromethane solution.
据报道,PhINTs和铜对环烷烃(cyclo-C(5)H(10),cyclo-C(6)H(12),cyclo-C(8)H(16))进行轻度催化脱氢和所得烯烃的叠氮化-[2.1.1]-(2,6)-吡啶并((L)与NaCur(F)(4)在二氯甲烷溶液中“活化”的LCuX(n)(n = 1,2; X = Cl,OTf)络合物。

linked, via all ortho positions through CH(2) or CH(2)CH(2) groups, bound to copper, gives good performance (rate and yield) catalyzing the conversion of substituted aliphatic olefins and PhINTs to aziridines. Advantages also derive from using CH(2)Cl(2) solvent and the weakly coordinating anions BAr(4)(-) (Ar = C(6)H(5) or 3,5-C(6)H(3)(CF(3))(2)). Reactions are complete in minutes at 20 degrees C, and

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。
