Abstract

Abstract An efficient and mild method using a bimetallic MnF 2/CuI catalyst at 60 C in water was developed for the N-arylation of amides and sulfonamides with aryl halides. A variety of functionalized amides and sulfonamides were coupled with different substituted aryl halides to afford the corresponding N-arylated products in good to excellent yields (up to 97%).
