An efficient and mild copper-mediated reaction for the direct perfluoroalkylation and difluoromethylation of indoles with perfluoroalkyl halides and ICF2COOEt to produce 2-substituted indoles was developed. Both free indole derivatives and N-substituted indole derivatives could be used in this process to obtain the desired products in moderate to good yields.

A mild and versatile approach for the directintroduction of ethoxycarbonyldifluoromethyl‐group to heteroarenesvia visible‐light photocatalysis has been developed. The new photoredox protocol has enabled the difluoromethylenation of heteroarenes containing a wide range of common functional groups under mild conditions.
