Abstract

Abstract Polyethylene glycol (mol. wei. 300–600) was found to be effective as a phase-transfer catalyst on the fluorination of activated halogen compounds with potassium fluoride in acetonitrile. Carboxylic and sulfonic acid chlorides were readily converted into their fluorides in high yields.
