The thermal isomerization of 3,3-dimethylcyclopropene under adiabatic-compression conditions at 660-850 K occurs in two independent directions with the formation of isopropylacetylene and isoprene; kinetic parameters for each of these routes were obtained.The formation of products of the gem-dimethylvinylcyclopropanation of olefins during their copyrolysis with 3,3-dimethylcyclopropene is not observed, apparently because of the occurrence of isomerization of 3,3-dimethylcyclopropene in the gas phase at 660-850 K without the participation of gem- dimethylvinylcarbene.
