Route to 1,1,1,2,2,3-hexachloropropane

Abstract

A one-step, low-yield route to 1,1,1,2,2,3-hexachloropropane by the aluminum chloride-catalyzed reaction of methylene chloride and tetrachloroethylene is described. Previously published procedures to this compound required fiveor six-step sequences based on carbon tetrachloride-ethylene or allyl chloride, respectively. P REVIOUSLY published routes to 1,1,1,2,2,3-hexachloropropane, (I), involve fiveor six-step sequences based on carbon tetrachloride-ethylene (4, 6) or allyl chloride (2, 18, 20), respectively.A one-step route to (I) would be the aluminum chloride-catalyzed alkylation of tetrachloroethylene with methylene chloride.
