An enantiomerically pure potential toxaphene congener: (1R,2S,3S,4R,7S)-2-endo,3-exo,5,5-tetrachloro-7-(chloromethyl)-1,7-bis(dichloromethyl)bicyclo[2.2.1]heptane

Abstract

A new enantiomerically pure potential toxaphene congener (C10H9Cl9) has been isolated from a reaction mixture obtained by the free radical chlorination of (1S)‐2‐endo‐chloro­bornane and its absolute configuration determined. It crystallizes in the monoclinic space group C2 with two mol­ecules in the asymmetric unit. This is the first report of the preparation of a single enantiomer of a synthetic poly­chloro­terpene on a multi‐milligram scale.
