New Syntheses of Chloro-Substituted Derivatives of Tropone The Diels-Alder reaction of donor-substituted 1.3-dienes with tetra chlorocyclopropene leads to novel bicyclo[4.l.0]heptenes, which on acidic hydrolysis and oxidalion yield a new series of chloro-substituted derivatives of tropone by way of elimination of hydrogen chloride concerted with an electrocyclic opening of the three membered ring.
