, (2020)
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 67–88percent yields. The reaction proceeds through a radical mechanism.

A Cu-mediated ligand-free arylation of NH-sulfoximines and sulfonamides by arylhydrazine hydrochlorides was herein demonstrated. The oxidative transformation provided an easy access towards N-aryl sulfoximines and sulfonamides in high yields (up to 93% yields) with broad functional groups tolerance (up to 36 examples). The protocol was proposed to take place through the free radical pathway based on the results of control reactions and EPR analysis.

N -Arylation of sulfoximines with different arylboronic acids, including sterically hindered boronic acids, is achieved using copper(I) iodide and 4-DMAP at room temperature. Moreover, N -arylation of biologically relevant l -methionine sulfoximine is demonstrated for the first time. All these reactions provided the desired products in excellent yields within a short span of time. The optimized reaction conditions are well suited to the task of N -vinylation of sulfoximine with trans -2-phenylvinylboronic acid.
