(Chemical Equation Presented) Green grow the diarylmethanes: Substituted arenes and heteroarenes can be easily benzylated in the presence of inexpensive and relatively nontoxic metal salts such as FeCl3 (see scheme). This arylation method with benzyl alcohols is a state-of-the-art green route to diarylmethanes as water is the only by-product.

An easily prepared Fe(iii)-derived Lewis acid ionic liquid ([C 4mim][FeCl4]), being comprised of 1-butyl-3-methyl imidazolium cation and tetrachloroferrate anion, was found to be an efficient, recyclable catalyst for benzylation of various arenes/heteroarenes into the diarylmethanes derivatives under mild reaction conditions without utilization of additional organic solvent. Interestingly, the acidity of [C 4mim][FeCl4] could account for its catalytic activity in promoting the Lewis acid-catalyzed alkylation. Notably, this type of Fe(iii)-based ionic liquid (IL) shows excellent stability, and could be easily recovered, and reused for five times without significant loss of its catalytic activity.
