Abstract
2-Hydroxy-4,6-dimethoxyacetophenone
and its acetate undergo nuclear bromination with cupric
bromide, and 2,3,4-trimethoxyacetophenone gave
w-bromo-2-hydroxy-3,4-dimethoxyacetophenone accompanied by a small yield of
2-hydroxy-3,4-dimethoxyacetophenone and by w-bromo-2,3,4-trimethoxyacetophenone.
Formation of the last compound was shown by isolation of
w-acetoxy-2,3,4-trimethoxyacetophenone after treatment of the mixture of
brominated products with sodium acetate in ethanol.
