Abstract

The method of fluorination using antimony pentachloride and anhydrous hydrogen fluoride^1^ has, by a simple modification, been extended to allow the almost quantitative conversion of the ‐C,Cl~3~ radical to ‐CF~3~, in chloroform, carbon tetrachloride, as‐tetrachloroethane, and methyl chloroform.
