摘要：
Protonation of the C≡C bond in trifluoromethyl-substituted arylacetylenes ArC≡CCF3 by the action of superacids (CF3SO3H or HSO3F) generates vinyl cations ArC+=CHCF3 which react with arenes Ar′H to give alkenes Ar(Ar′)C=CHCF3. Protonation of the latter at the C=C bond in the reaction medium yields stable cations Ar(Ar′)C+-CH2CF3 which are converted into E/Z-isomeric alkenes Ar(Ar′)C=CHCF3 and/or alcohols Ar(Ar′)C(OH)CH2CF3 as a result of quenching of superacid reaction solution.
