The reactivity of a series of polyfluorinated 2-alkynylanilines with various alcohols using p-TSA has been studied. It was found that hydration of the triple bond gave rise to polyfluorinated 2-aminoarylketones and competed with an electrophilic heterocyclization reaction leading to polyfluorinated indoles. The dependence of the reaction pathways on the nature of the alkynylaniline substituents has been examined. (C) 2015 Elsevier Ltd. All rights reserved.
