Abstract
Norbornadiene and isoprene are catalytically codimerized to an olefinic codimer. Used is a three-component homogeneous catalytic system consisting of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride. The codimer upon hydrogenation forms .beta.-methyltetramethylene nortricyclane having utility as a diluent for a high energy hydrocarbon missile fuel.
