Scheme 1.

Scheme 1

Existing and new reaction modes of halogenated anhydrides. A) Divergent synthesis in photocatalysis. B) Notable examples of gem‐difluoromethylene (CF2) containing biorelevant structures. C) Established and new activation modes of anhydrides. D) Photoredox activation of CDFAA for the switchable synthesis of gem‐difluoro cyclic and acyclic compounds.
