Simultaneous introduction of trifluoromethyl and λ6-pentafluorosulfanyl substituents using F5S–CC–CF3 as a dienophile

Abstract

SF₅–CC–CF₃ as a powerful dienophile in Diels–Alder reactions, provides the corresponding products in up to quantitative yields and allows the introduction of the pentafluorosulfanyl group and trifluoromethyl group at the 1,2 position.
