Copper-Mediated -Selective C(sp)-H Functionalization of Carboxylic Acid Derivatives with N(sp)-H Sulfonimidamides: A Mild and General Strategy for C-N Bond Formation.

Herein, we report the copper (Cu)-mediated selective C-H bond functionalization of easily accessible N(sp)-aryl derivatives of hexavalent, diazaanalogs of sulfones such as sulfonimidamides (SIAs) with carboxylic acid derivatives decorated with oxazolidine. The -C-H bonds of aryl amides underwent a smooth reaction with the N(sp)-H bonds of a variety of sulfonimidamides (SIAs). The reaction offers a broad array of C-N(sp) bond derivatives with good functional group tolerance in good yields under mild reaction conditions in an selective manner.
