Abstract
IT is well known that both isodrin and endrin produce compounds containing a rearranged carbon skeleton when treated with acids, heat or ultra-violet light1–3. Both thermal and acid-catalysed decompositions of endrin yield mainly a ketone which has the same elementary formula as endrin but contains an additional five-membered ring and has lost the olefinic double-bond. This communication reports an instance in which a pure, recrystallized sample of endrin stored in the dark for several years under normal ambient temperature conditions underwent this rearrangement.
