Method for the preparation of fluoroaniline

摘要

A process for the preparation of fluoroaniline compounds comprises the steps of (A) reacting an ammonium fluorophthalamate or a fluorophthalamic acid of the formula <IMAGE> where n is 1 or 2 with an alkali or an alkali earth metal hypochlorite to form the corresponding fluoroanthranilic acid; and (B) decarboxylating the fluoroanthranilic acid by reaction with a mineral acid to form the corresponding fluoroaniline of the formula <IMAGE> where n is as previously defined.
