Abstract

a. Procédé de fabrication de 2,3 : 5,6-bis(cycloalkéno)-pyridines à partir de cycloalcanones. b. Procédé consistant essentiellement à faire réagir des cycloalcanones, ayant au moins un groupe méthylène réactif adjacent au groupe céto, avec des aldéhydes aliphatiques et du gaz ammoniac, en phase gazeuse, en présence d'un catalyseur à action déshydratante et déshydrogénante, à des températures d'environ 250 à 550 degrés C. c. L'invention trouve son application principale dans les fabrications de bis(cycloalkéno)-pyridines, servant de produits intermédiaires notamment pour la fabrication de médicaments, d'agents de protection des plantes et de matières plastiques.at. Process for the production of 2,3: 5,6-bis (cycloalkeno) -pyridines from cycloalkanones. b. A process consisting essentially of reacting cycloalkanones, having at least one reactive methylene group adjacent to the keto group, with aliphatic aldehydes and ammonia gas, in the gas phase, in the presence of a catalyst with dehydrating and dehydrogenating action, at temperatures of 'about 250 to 550 degrees C. c. The invention finds its main application in the manufacture of bis (cycloalkeno) -pyridines, serving as intermediate products in particular for the manufacture of drugs, plant protection agents and plastics.
