Abstract
The present disclosure relates to reagents and method for performing trifluoromethylation, difluoromethylation or alkylation of aromatic or heteroaromatic rings in a redox-neutral manner without any catalyst which are enabled by light. In addition, there are methods for synthesizing the starting reagents used in the trifluoromethylation, difluoromethylation or alkylation reactions.
