systems for copper-catalyed N-arylations of sulfoximines with arylbromides and aryliodides have been developed. Using 10 mol % of a copper(I) salt in combination with 20 mol % of a 1,2-diamine and Cs2CO3 provides N-arylated sulfoximines in high yields. Various functional groups and heteroatoms are tolarated. The method is complementary to the known protocols for N-arylations of sulfoximines, which require
已经开发了两种简单且廉价的系统,用于亚砜基与芳基溴化物和芳基碘化物的铜催化的N-芳基化。将10摩尔%的铜(I)盐与20摩尔%的1,2-二胺和Cs 2 CO 3结合使用,可以高收率得到N-芳基化亚砜基。各种官能团和杂原子是对等的。该方法是对亚砜亚胺N-芳基化的已知方案的补充,后者需要化学计量的铜盐或成本昂贵的钯/ BINAP催化剂。

The efficient N-arylation of a sulfoximine with aryl chlorides was developed by using Pd2(dba)3 as a catalyst and various ligands. The reactions using RuPhos as a ligand afforded the coupled products in fair to excellent yields.
