Abstract

The presence of catalytic amounts of 3-methyl-1-sulfonic acid imidazolium tetrachloroaluminate ([Msim]AlCl4) or silica sulfuric acid (SSA) enables an efficient benzylation of a range of aromatic compounds by benzyl acetate under mild conditions. Simple methodology, easy workup procedure, clean reaction and reusability of the catalyst are some advantages.
