The reaction of PhI=NTs with sulfoxides in the presence of catalytic amounts of copper(II) salts afforded the corresponding N-tosylsulfoximines in high yield. This method is highly tolerant to reaction conditions (no needof distilled solvents and/or inert atmospheres) and allowed the formation of previously unknown acetylenic sulfoximines with complete retention of configuration at sulfur.
在催化量的铜 (II) 盐存在下,PhI=NT 与亚砜的反应以高产率提供了相应的 N-甲苯磺酰基亚砜亚胺。该方法对反应条件具有高度耐受性(不需要蒸馏溶剂和/或惰性气氛),并允许形成以前未知的炔属亚砜亚胺,并在硫中完全保留构型。
