    摘要: Novel codimers (I) of norbornadiene and phenylacetylenes and their hydrogenated derivatives (II), having the following structures ##STR1## wherein R is a hydrogen, a phenyl, or a phenyl having alkyl substituents and R.sub.1 is a phenyl or a phenyl having alkyl substituents and processes for preparing both are disclosed. Codimer (II) can be used as a high energy fuel or a diluent for such a fuel. Process for making codimer (I) involves reacting norbornadiene and phenylacetylene or diphenylacetylene with a catalyst system of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride.

    摘要: 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.

    摘要: Alkanes are catalytically oxidized in air or oxygen using iron-substituted polyoxoanions (POAs) of the formula: H.sub.e-z �(n-C.sub.4 H.sub.9).sub.4 N!.sub.z (XM.sub.11 M'O.sub.39).sup.-eThe M' (e.g., iron(III)/iron(II)) reduction potential of the POAs is affected by selection of the central atom X and the framework metal M, and by the number of tetrabutyl-ammonium groups. Decreased Fe(III)/Fe(II) reduction potential has been found to correlate to increased oxidation activity.
