Bao, Rui-Peng published the artcileIr(III)-Catalyzed Mono-Olefination of Aryl C-H Bonds Using -SCF3 as a Weak Directing Group, Category: bromides-buliding-blocks, the publication is Organic Letters (2019), 21(19), 8116-8121, database is CAplus and MEDLINE.
The trifluoromethylthionyl group (-SCF3) is an efficient weak directing group for Ir(III)-catalyzed aryl C-H olefination. Various trifluoromethylthioethers provide high levels of mono-olefination products in good to excellent yields under mild conditions with a 2,2′-bipyridine ligand or AgBF4 as an additive. Mechanistic studies indicate the C-H cleavage is the rate-determining step. The directing group ability of the -SCF3 group is benchmarked against several other weak directing groups by competition experiments under Ir(III)-catalyzed conditions.
