Abstract
Processes for preparing vinyl nortricyclane (I) and its hydrogenated derivative, ethyl nortricyclane (II) are disclosed. The nortricyclane (II) can be used as a high energy fuel or a fuel diluent. Process involves codimerization of norbornadiene and ethylene in the presence of a homogeneous catalytic system of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride to yield the vinyl nortricyclane (I). The latter can be hydrogenated to ethylnortricyclane.
