Chemistry of Heterocyclic Compounds Aims and scope

Abstract

In the presence of catalysts (Al2O3, Al2O3 activated by HCl, and 5, 10, and 20% ZnCl2/Al2O3), 2- and 3-methylbenzothiophenes undergo mutual isomerization, dealkylation, and disproportionation to benzothiophene and 2,3-dimethylbenzothiophene at 250–450°C and space velocities of 0.1 and 0.8 h−1. An ionic mechanism is proposed for the isomerization reaction.
