Abstract

Xa and Xb) is nearly independent of the experimental conditions and probably promoted by the resulting aromatization. lo Removal of the angular chlorines from the derivatives of both chloranil I and 2, 5-dichloroquinone (IV) was accomplished also by catalytic low-pressure hydrogenations over palladium-oncharcoal or platinum oxide. The latter also effected saturation of the isolated double bond. The nature of the products (X and XI) was in-
