Abstract

A nickel-catalyzed aromatic C-H alkylation with tertiary or secondary alkyl-Br bonds enables the construction of indolones. The reaction tolerates various functional groups. Moreover, challenging secondary alkyl bromides can also be transformed. Radical trapping and photocatalysis conditions exhibited that a radical process is involved in this aromatic C-H alkylation.
