    摘要: Binor-S is prepared by the dimerization of norbornadiene (bicyclo[2.2.1]hepta-2,5-diene) at an excellent conversion and an excellent selectivity using an effective amount of a two component catalytic system of tris(triphenylphosphine)rhodium chloride and diethylaluminum chloride or ethylaluminum dichloride or aluminum ethylsesquichloride. The range of mole ratio of norbornadiene to tris(triphenylphosphine)rhodium chloride is between from about 100 to about 1000 and the range of mole ratio of one of the aluminum chlorides to the rhodium chloride is between from about 0.5 to about 100. The reaction rate is rapid. Binor-S can be used as precursor for hydrocarbons having utility for either jet or rocket propulsion.

    摘要: Norbornadiene [bicyclo (2.2.1) heptadiene-2,5] is dimerized to a mixture of mainly the exo-endo stereoisomer of the hexacylic dimer of norbornadiene at both an excellent selectivity and conversion using an effective amount of a two component catalytic system of rhodium acetylacetonate and diethylaluminum chloride or ethylaluminum dichloride or aluminum ethylsesquichloride. The mixture also contains the endo-endo stereoisomer and some trimer. After hydrogenation a suitable mixture of the exo-endo and endo-endo dimers can be used as a component of high energy fuel.

    摘要: Norbornadiene and an acrylic acid ester, e.g., methyl acrylate, are catalytically codimerized in the presence of a two-component homogeneous catalytic system consisting of nickel acetylacetonate and an alkyl aluminum chloride. The resulting codimer can be used as a precursor for a missile fuel. The ester portion of the acrylic acid ester is the radical RCH.sub.2 O-- wherein the R is an H or an alkyl containing up to 10 carbon atoms.
