The Friedel-Crafts reaction is a typical electrophilic substitution reaction in the aromatic nucleus; the role of the catalyst amounts to the generation of an attacking particle—an alkyl or acyl cation. Examples are given below of the interaction of benzene with the ethyl chloride and the acid ...

Since alkyl Lewis acids are Br0nsted bases, they give a non-acidic reaction media. In this context, acylation of thiophene is investigated in the presence of EtAlClz and non-acidic media. Besides 8 examples of thiophene, one example for pyrrole is synthesized in moderate to high yields (up...

What is the major product in the Friedle-Craft Alkylation reaction using 1,4-dimethoxybenzene and 3-methyl-2-butanol, also included in the reaction are H_2SO_4 and CH_3COOH. What is the mechanism behind this reaction? What is the structure and I...
The reaction of glutaric anhydride with benzene and toluene has been thoroughly studied. 4,4-Diphenyl-pent-4-enoic acid and 1,3-dibenzoyl propane were isolated as by-products of the reaction with benzene. The mechanism of formation of the by-products has been proved. In case of toluene no ...
