Abstract:
A pyridine-compound is reacted with fluorine together with a .[.Bronsted.]. .Iadd.Bronsted .Iaddend.acid-compound or Lewis acid to form a N-fluoropyridinium salt which is very active to other compounds but is very selective for the preparation of a desired product and this product is very useful for a fluorine-introducing agent which makes it useful for the preparation of fluoro-compounds such as thyroid inhibitor.
