摘要：
N-Arylation of sulfoximines with aryldiazonium tetrafluoroborates is demonstrated in the presence of copper chloride and DABCO. A wide range of aryl and alkyl sufoximines are participated in the coupling reaction with different aryldiazonim salts bearing electron donating and withdrawing groups and provided the desired products in 67-88% yields. The reaction proceeds through a radical mechanism. (C) 2020 Elsevier Ltd. All rights reserved.
