Abstract
Process for the production of 2,5-dimethyl-1,5-hexadiene by heating isobutene with a 1,1,2-trihalo ethylene in the vapor phase in the presence of a free-radical generator. The free-radical generator is preferably a peroxide and the reaction temperature in the range 200.degree.-600.degree. C. The product may be readily isomerized to 2,5-dimethyl-2,4-hexadiene, which is useful as an insecticide intermediate.
