| titleOfInvention | Process for preparing fluoropyridine compounds |
| abstract | A process for preparing a fluoropyridine compound by reacting a chlorinated pyridine compound with a molar excess of an alkali metal fluoride, especially potassium fluoride, in the presence of a catalytic amount of a catalyst selected from halides of organometals and halides of metals of the iron, nickel and copper groups, and which is preferably FeCl 3 , whereby at least one chlorine atom of the chlorinated pyridine compound is replaced by a fluorine atom. Of special interest is the preparation of 3,5-dichloro-2,4,6-trichloropyridine from pentachloropyridine. n The compounds prepared by such a process are useful for the preparation of agriculturally-useful fluoropyridines. |
