3-Nitro-substituted phenacyl bromides
Abstract
3-Nitrophenacyl bromides of 4-bromo-, 4-chloro-, 4-methyl-, and 4-hydroxy-acetophenones are obtained in excellent yield by the nitration of the corresponding phenacyl bromides in fuming nitric acid (d, 1·42) at 5°. Nitration of 4-phenylphenacyl bromide yields 3-nitro-4-(4-nitrophenyl)phenacyl bromide. The identity of these products has been established by inverse substitution with acidified potassium iodide solution.
