The copper(I)-catalyzed free radical addition of halomethanes to acrylates and the addition of halogenated acetic acid derivatives to fluoro- or chloro-substituted ethylenes affords polyhalogenated butyric acid derivatives.Chlorides of these acids serve as precursors for haloketenes used in efficient syntheses of pyrethroids.
