Abstract

Copyrolysis of difluorochloromethane with methylcyclopentadiene under conditions of pulsed gas compression at 924–1157 K takes place with the participation of difluorocarbene and a mixture of isometric fluorotoluenes with a total yield of 66–68% is formed. In the absence of CHClF2, methylcyclopentadiene under conditions of pulsed compression at 1019–1190 K undergoes partial transformation into benzene and cyclopentadiene.
