A general para‐selective C‐H functionalization was achieved via a stericcontrol strategy. Para‐iodo, bromo, chloro, nitro, and trifluormethyl aniline derivatives were prepared via in situ generated, bulky hypervalent iodinium reagents in as little as 10 min. Products can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work‐up

efficient and practical methodology for the synthesis of N-arylamides has been developed via copper-catalyzed amidation of diaryliodonium salts with nitriles. Various substituted aryl nitriles and aliphatic nitriles could be applied in the reaction, providing a series of N-arylated amides in moderate to good yields. This procedure provides an alternative route for the synthesis of various N-arylamides
