Method for preparing 1,1,1,3,3-pentachlorobutane

摘要

Halohydrocarbons comprising at least 3 carbon atoms are obtained by reaction between a haloalkane and an olefin in the presence of an organocopper compound as catalyst, a solvent and/or a cocatalyst. 1,1,1,3,3-Penta-chloropropane can thus be obtained in good yield under mild conditions.
