The reaction of hexachlorocyclopentadiene as a diene in Diels-Alder type reactions is well known, and reviews on this subject are avai1able. lbJ The biological activity of a number of highly chlorinated compounds prompted the preparation of a few additional 2-oxygenated 1, 4, 5, 6, 7, 7-hexachloro-5-norbornenes, and their characterizations are reported herein.
