Abstract
Isobutene is oxidatively coupled with vinylidene chloride by heating in the presence of palladium acetate, to give 1,1-dichloro-4-methylpenta-1,3-diene. This compound is useful as an intermediate in the production of insecticides. Any 1,1-dichloro-4-methylpenta-1,4-diene also produced is thermally isomerized to the 1,3 product.
