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.
