Preparation of fluoroorganic compounds with calcium fluoride

摘要

Fluoroorganic compounds are prepared by reacting a haloorganic starting material in which at least one halo atom is replaceable with a fluorine atom by metathetical exchange, with calcium fluoride in the presence of a crown ether and an anhydrous, polar, basic organic solvent which complexes with the calcium ion and contains no -OH groups, at a temperature and for a period of time adequate to effect fluorination.
