Convenient preparation of 1,4-dibenzylbenzene using zinc chloride in the presence of polar solvents

1,4-Dibenzylbenzene was successfully synthesized by the Friedel-Crafts benzylation of benzene with 1,4-bis(chloromethyl)benzene using zinc chloride in the presence of polar solvents. In particular, zinc chloride dissolved in primary alcohols or ketones with a molar ratio of 1 was a highly effective catalytic system in the reaction.

Benzylation of benzene by benzyl chloride over silica-supported iron sulfate catalysts

The silica-supported Fe-containing catalysts prepared using FeSO 4 as a precursor exhibit high activity toward the reaction of benzene with benzyl chloride.

Selective synthesis of 1,4-dialkylbenzenes from terephthalic acid

Terephthalic acid reacts with alkyl halides under Birch conditions to substituted 1,4-cyclohexadienes in high yields and good stereoselectivities. Electrophiles containing ester or nitrile groups undergo a surprising fragmentation under the reaction conditions. Subsequent treatment with chlorosulfonic acid proceeds by an interesting tandem decarbonylationldecarboxylation, affording 1,4-dialkylbenzenes in excellent regioselectivity. Thus our new method is superior to classical Friedel-Crafts alkylations.
