Reversible structural isomerization of 1,3- and 1,2-dimethylsubstituted cyclopentadienes, proceeding according to a mechanism of 1,2-shift of the methyl group from the 5-position of the cyclopentadiene ring, accompanied by the migration of the system of intracyclic double bonds, is carried out at the temperatures 400–500°. In conjunction with the 1,2-shift of hydrogen, the indicated conversion leads to the formation of an equilibrium mixture of structural isomers, containing 38% 1,3-dimethylcyclopentadienes and 62% 1,2-and 2,3-dimethylcyclopentadienes (total).
