The bromination of some derivatives of resorcinol

Abstract

The bromination of 3,5-dimethoxytoluene (1), 3-hydroxy-5-methoxytoluene (22), methyl 2-hydroxy-4-methoxy-6-methylbenzoate (27), methyl 3,5-dimethoxybenzoate (36), and 3,5-dihydroxybenzoic acid (42) has been investigated. Hydrogen bromide-catalysed rearrangements encountered in these studies are described.
