Sustainable, precious-metal-free C-N cross coupling through photocatalysis

Photoredox catalysis has evolved as a sustainable method of constructing C-N bonds. Herein, we have reported a visible-light organic-photoredox-catalyzed method that enables C-N cross-coupling under mild and sustainable reaction conditions. This catalytic system is suitable for both aromatic and aliphatic amines, as well as electron-rich and -deficient aryl bromides, exhibits broad functional group tolerance, and provides good-to-excellent yields. The noteworthy aspects of milder reaction conditions at room temperature without the addition of any additional ligands make this procedure attractive.
