An efficient synthesis of diarylmethanes via InCl3*4H2O-catalyzed dehydration of electron-rich arenes with trioxane

A facile, efficient and environmentally benign procedure for the synthesis of diarylmethanes via the reaction of arenes with trioxane catalyzed by InCl3*4H2O was developed. The reactions of aromatic compounds bearing electron-donating group proceeded smoothly affording the corresponding diarylmethanes in good to excellent yields.

SYNTHESIS OF SUBSTITUTED 2,4,5-TRIMETHYLDIPHENYLMETHANES

2,5-Dimethyldiphenylmethane and its 2'- and 4'-methyl, chloro, and nitro derivatives were obtained by the reaction of substituted benzyl chlorides with p-xylene in the presence of ferric chloride and zinc stearate.The yields of the 2,5-dimethyldiphenylmethanes depend on the nature of the substituent in the benzyl chloride and decrease with the substituents in the order NO2>Cl>H>CH3.The 2' and 4'-methyl, chloro, and aminoderivatives of 2,4,5-trimethyldiphenylmethane were synthesized by chloromethylation of the obtained diphenylmethanes with paraform in acetic acid in the presence of zinc chloride followed by reduction of the 2,5-dimethyl-4-chloromethyldiphenylmethanes with zinc in acetic acid.
