Roles reversed: An efficient cobalt‐catalyzed electrophilic amination of arylzinc reagents has been achieved. A variety of functionalized arylzincs and N‐chloroamines were coupled under mild conditions (see scheme). Both secondary and tertiary arylamines were obtained in moderate to excellent yields.

A one-pot synthesis of amidesfrom aldheydes with N-chloroamines, prepared in situ from amines, has been developed. Both aliphatic and aromatic aldehydes and many types of mono- and disubstituted amines are tolerant in this transformation. This cross-coupling reaction appears simple and convenient, has a wide substrate scope and makes use of cheap, abundant, and easily available reagents.
