straightforward synthesis of halogen‐containing quinolin‐2(1H)‐ones. The reaction proceeds without preactivation and directing groups through direct N–H and C–H bondactivation with a broad substrate scope and high efficiency. Halogen functional groups can be well tolerated here. Remarkably, this is the first example of an iridium‐catalyzed carbonylative C–H activation of anilines.

Preparation of α,β-Unsaturated Lactams through Intramolecular Electrophilic Carbamoylation of Alkenes
β-unsaturated lactams starting from alkenylchloroformamides has been developed. The reaction was complete within five minutes at 150 ˚C in N-methylpyrrolidone with a catalytic amount of HBr under microwave irradiation. Not only six-membered lactams, but also five- and seven-membered lactams were obtained in high yields. lactam- cyclization - electrophilic addition -acid catalyst - microwave

An atom-efficient silver-catalysed double carboxylative strategy for the one-step synthesis of quinolin-2-ones via an addition–cyclisation–elimination cascade sequence of oxamic acids to acrylic acids, mediated either thermally or photochemically, is reported. The reaction was applicable to the synthesis of a broad range of quinolin-2-ones and featured a double-disconnection approach that constructed
