Unlocking the direct photocatalytic difluoromethylation of C[double bond, length as m-dash]N bonds.

The current study presents a direct CF2H radical addition to C & xe001;N bonds predicated on the photocatalytic activation of commercially available zinc difluoromethanesulfinate. The mild conditions in place lead to impressive structural diversity, as quinoxalinones and dibenzazepines, among others, are successfully functionalized.
