Fluorophthalamic acids and method of preparation |
| abstract |
Fluorophthalamic acids characterized by the formula ##STR1## wherein n is 1 or 2, are prepared by the steps of n (A) reacting a chlorophthalic anhydride of the formula ##STR2## where n is as defined previously, with potassium fluoride or cesium fluoride to form a fluorophthalic anhydride of the formula ##STR3## where n is as previously defined, and (B) reacting the fluorophthalic anhydride with ammonia to form an ammonium salt of a fluorophthalamic acid, and n (C) acidifying the ammonium salt to form a fluorophthalamic acid. |
