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.
