Nickel(<scp>ii</scp>)-catalyzed tandem C(sp2)–H bond activation and annulation of arenes with gem-dibromoalkenes

A nickel(II)/silver(I)-catalyzed tandem C(sp2)–H activation and intramolecular annulation of arenes with dibromoalkenes has been successfully achieved, which offers an efficient approach to the 3-methyleneisoindolin-1-one scaffold. Attractive features of this system include its low cost, ease of operation, and its ability to access a wide range of isoindolinones.
