Method for the preparation of fluorophthalamic compounds. |
摘要 |
<p>Novel compounds and their preparation are disclosed comprising: (A) reacting a chlorophthalic anhydride of the formula <CHEM> wherein n is 1 or 2, with potassium fluoride or cesium fluoride to form a fluorophthalamic anhydride of the formula <CHEM> (B) reacting the fluorophthalic anhydride of (A) with ammonia to form a novel ammonium fluorophthalamate; (C) acidifying the ammonium fluorophthalamate of (B) to form a novel fluorophthalamic acid; (D) dehydrating the fluorophthalamic acid of (C) to form a novel fluorophthalimide; and (E) reacting the fluorophthalimide of (D) with an alkali metal salt to form a novel alkali metal fluorophthalamide.</p> |
