ABSTRACT:
Norbornadiene and an alkyne are catalytically codimerized in the presence of a homogeneous catalytic system of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl alluminum chloride. Also, novel codimers of norbornadiene and an alkyne containing at least three carbons are disclosed. After hydrogenation, resulting codimers can be used as high energy fuels or diluents for such fuels.
