Chemistry of Heterocyclic Compounds Aims and scope

Abstract

When benzofuran is alkylated with tert-butyl chloride in the vapor phase (190–260‡C) in a flow system, the ratio of the 2- and 3-tert-butylbenzofurans formed varies from 2∶1 to 20∶1, depending on the acidity of the catalyst used (ZnCl2/Al2O3), because of conversion of the 3-isomer to the 2-isomer.
