Fluorination of organic compounds with anhydrous hydrogen fluoride. Part I. The preparation of fluoroform and certain derivatives

Abstract The method of fluorination using antimony pentachloride and anhydrous hydrogen fluoride1 has, by a simple modification, been extended to allow the almost quantitative conversion of the ‐C,Cl3 radical to ‐CF3, in chloroform, carbon tetrachloride, as‐tetrachloroethane, and methyl chloroform.
