    Abstract: The invention comprises vinyl 1,4,5,6,7,7-hexachlor - bicyclo - (2, 2, 1) - heptene - (5) - 2 - carboxylate of formula It is prepared either by the Diels-Alder condensation of hexachlorcyclopentadiene with vinyl acrylate or by the Diels-Alder condensation of hexachlorcyclopentadiene with acrylic acid and the liquid- or gas-phase vinylation of the resulting acid with acetylene in the presence of a compound of a metal of Group IIb. A polymerisation inhibitor may be present during the preparation. Polymers of the ester may be used in flame-resistant varnishes and car finishes. Specification 794,621 is referred to.

    Abstract: 1,151,574. Cycloalkanols and cycloalkanones. BADISCHE ANILIN- & SODA FABRIK A.G. 16 Sept., 1966 [17 Sept., 1965], No. 41468/66. Heading C2C. A mixture of a cycloalkanol and a cyclealkanone is obtained from a cycloalkane having 5-12 ring atoms by contacting the cycloalkane with molecular oxygen at a temperature of about 80-200‹ C., a pressure to maintain the reaction mixture in the liquid phase and in the presence of a cycloalkane oxidation catalyst and a minor amount of an olefinically unsaturated compound containing 3-20 carbon atoms which can be epoxidized under the reaction conditions. Suitable cycloalkane oxidation catalysts are, for example, the salts of vanadium, chromium, manganese, molybdenum, iron, cobalt or nickel with lauric acid, oleic acid, palmitic acid, stearic acid and naphthenic acids or the acetylacetonates, acetonylacetonates or carbonyls of these metals. Suitable olefinically unsaturated compounds are unsaturated hydrocarbons or those containing halogen, hydroxyl, carboxyl, ester or ether substituents. Examples are given of the oxidation of cyclohexane and cyclooctane.
