硫杂杯[3]吡啶铜配合物[Cu-（Py 3S 3）]（2）（PF 6）（2）是一种有效的烯烃氮丙啶化催化剂。苯乙烯（1当量）与PhI=NTs（1当量）在20 ℃下在1.2mol%催化剂存在下在需氧条件下反应产生N-（对甲苯磺酰基）-2-苯基氮丙啶（71%，转换数= 55）。当催化剂用量为0.12 mol%，苯乙烯/PhI=NTs比为5：1时，转化率可达350，产率为41%。
A copper(I) complex with thiacalix[3]pyridine, [Cu-(Py3S3)](2)(PF6)(2), is a competent catalyst for aziridination of olefins. The reaction of styrene (1 equiv) with PhI=NTs (1 equiv) at 20 degrees C produced N-(p-toluenesulfonyl)-2-phenylaziridine (71%, turnover number = 55) in the presence of 1.2 mol% catalyst under aerobic conditions. The turnover number increased up to 350 with a 0.12 mol% catalyst and a 5:1 styrene/PhI=NTs ratio in 41% yield.
