KINETICS AND MECHANISM OF THE SYNTHESIS OF DIFLUOROBENZENES BY THERMAL REACTION OF DIFLUOROCARBENE WITH BUTADIENE

Reaction of butadiene with difluorocarbene, resulting in the formation of difluorobenzenes, and its main steps have been systematically studied.The kinetics of thermal conversions of intermediately formed 2,2-difluorovinylcyclopropane and 2,2,3,3-tetrafluorovinylcyclobutane has been examined.The synthesis of difluorobenzenes has been optimized.The results obtained are used as a basis for domestic technology of production of difluorobenzenes.

Heats of Hydrogenation, III. Influence of Fluoro Substituents on the Thermal Rearrangement of Cyclopropane Systems

The influence of the fluoro substituents on the isomerisation of 1,1-difluoro-2-vinylcyclopropane (1) and of cis-1,1-difluoro-2-methyl-3-vinylcyclopropane (11) is demonstrated by kinetic methods and by heat of hydrogenation measurements to be a ground state effect (destabilisation of the cyclopropane by 12 - 14 kcal/mol).The transition states of the vinylcyclopropane rearrangement of 1 and of the 1,5-homodienyl hydrogen shift of 11 are more or less effected, depending on their cyclopropane character.
