6,7,8,9-Tetrachloro[1,3]oxazepine-1,5-dione derivatives 1b-10b have been synthesized by reacting Schiff bases 1a-10a with tetrachlorophthalic anhydride (TCPA) under (2 + 5 → 7) cycloaddition reaction conditons. All reactions had been monitored using TLC.

Ir-catalyzed sp2C?H amidation of aldehydes with various anilines as stoichiometric or catalytic directing groups was accomplished. A wide range of substrates were selectively amidated in good to excellent yields with broad functional group tolerance. The iridacycle complexes were isolated, characterized, and proved as key intermediates. Kinetic studies and Hammett plots provided detailed understandings of this amidation. According to the mechanism, the electron-rich ArSO2N3was proved effective for intermolecular sp3C?H amidation.
