A study was carried out on the electrophilic substitution reactions in benzene and toluene by the action of ClCH2OCH3 in the presence of trivalent lanthanide salts, LnCl3, where Ln = Ce, Dy, Er, and Sm(O3SCF3)3 as the catalysts, at room temperature over 24 h.These lanthanide salts display the properties of weak but hard Lewis acids.The raection proceeds exclusively by chloromethylation with the subsequent formation of diarylmethanes.
