Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Depending on the reaction conditions, the bromination of 3-acyl-5-hydroxybenzofurans leads to 4-bromo and 4,6-dibromo derivatives, whereas chlorination leads to replacement of the hydrogen atom in the 4 position. As in the nitration of 3-acyl-5-hydroxybenzofurans with a nitrating mixture, 3-acyl-4,6-dinitro-5-hydroxybenzofurans are formed in the nitration of 3-acyl-5-hydroxybenzofurans with nitric acid.
