Trifluoromethylation of Alkenyl Bromides and Iodides (Including 5-Iodouracils) with (CF3)2Hgand Cu (“Trifluoromethylcopper”)1
摘要:
[GRAPHIC]Bromo- and iodoalkenes undergo trifluoromethylation efficiently in DMA with "CF3Cu" generated from (CF3)(2)Hg and Cu. Variable stereochemical inversion is observed with substrates having a gem-carbonyl group. Substrates having gem-hydrogen, -alkyl, or -alkenyl groups give products with stereochemical retention.
