Brønsted acidic ionic liquid: a simple, efficient and recyclable catalyst for regioselective alkylation of phenols and anti-Markovnikov addition of thiols to alkenes

Abstract

A highly efficient protocol for the alkylation of phenols and anti-Markovnikov addition of thiols with various alkenes has been developed using a Brønsted acidic ionic liquid, N-methyl-2-pyrrolidone hydrogen sulfate [NMP]+HSO4, under solvent free conditions. The developed methodology offers appreciable advantages with respect to excellent yield, short reaction time and high regioselectivity. The C–C and C–S bond formation has been achieved under metal free conditions.
