Copper(I) bromide‐catalyzed amidation of 2‐arylpyridine derivatives and 1‐methylindoles with a variety of amides was achieved by employing tert‐butyl peroxide (TBP) as oxidant. Aryl halides could be tolerated under the reaction conditions. Neither a special ligand nor a base was required for this amidation process.

Rh(III)-catalyzed intermolecular direct aromatic C–H bond amidation with amides has been accomplished under mild reaction conditions. This protocol is applicable to a broad range of N-chelator-containing arenes amidated with aromatic and aliphatic sulfonamides. A possible mechanism is proposed according to the experimental results.

transition‐metal‐catalysedC−Hamidation procedure is reported. Dibenzothiophene‐based sulfilimines were shown to constitute a class of novel amidation reagents which enable the transfer of a wide range of N‐sulfonyl and N‐acyl moieties. It was demonstrated that sulfilimines, which are easily accessible from cheap reagents, are safe‐to‐handle and represent broadly applicable amidation reagents. The dibenzothiophene
