Copper(0)-mediated fluoroalkylation of iodobenzene with 2-bromo-1,1,2,2-tetrafluoroethyl compounds: Investigation on the influence of R substituent on the reactivity of RCF2Cu species

Add time:09/25/2019    Source:sciencedirect.com

We have made a systematic investigation on the copper(0)-mediated tetrafluoroethylenation of iodobenzene with structurally diverse 2-bromo-1,1,2,2-tetrafluoroethyl compounds. A comparison of this reaction with 1,2,2-trifluoro-1-phenylethylation and the known functionalized difluoroalkylation demonstrates that the substituent R of α,α-difluoroalkyl copper species RCF2Cu plays a crucial role on their reactivity, which is believed to be useful for the development of new fluoroalkylation reactions under the promotion of transition metals.
