Efficient hydroarylation and hydroalkenylation of vinylarenes by Brønsted acid catalysis

Abstract

Brønsted acid Tf₂NH-catalyzed hydroarylation and hydroalkenylation of 4 vinylarenes under mild reaction conditions is herein shown to provide access to 1,1-diarylalkane scaffolds and trans-1,3-diaryl-1-butenes in high yields and with excellent regioselectivity.
