Photoorganocatalysed and visible light photoredox catalysed trifluoromethylation of olefins and (hetero) aromatics in batch and continuous flow

Trifluoromethylation of olefins and (hetero) aromatics with sodium triflinate as CF3 source and readily accessible benzophenone derivatives as photosensitisers has been developed in batch and flow. The use of an iridium-based photocatalyst enables the trifluoromethylation to proceed under visible light irradiation.
