The Suzuki-Miyaura reaction of 1,4-dibromo-2-(trifluoromethyl)benzene provides a convenient route for the synthesis of various trifluoromethylated di- and terphenyls. The reactions proceed with excellent site selectivity in favor of the 4-position due to steric and electronic reasons.
Synthesis of trifluoromethyl-substituted bi- and terphenyls by site-selective Suzuki–Miyaura reactions of various dihalogenated trifluoromethyl-benzene derivatives
A variety of trifluoromethylated bi- and terphenyls were prepared by site-selective Suzuki-Miyaura cross-coupling reactions of various dihalogenated trifluoromethyl-substituted benzene derivatives. The reactions proceed with excellent site-selectivities. (c) 2012 Elsevier B.V. All rights reserved.
