摘要:
Norbornadiene and 1,3-pentadiene are catalytically codimerized to an olefinic codimer using a three-component homogeneous catalytic system of cobaltic or cobaltous acetylacetonate, triphenylphosphine and an alkyl aluminum chloride. The codimer, after hydrogenation, has utility as a high energy missile fuel or a diluent for a higher viscous missile fuel.
摘要:
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.
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 substitutents 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.

Norbornadiene and nobornene are catalytically codimerized to the saturated exo-exo hexacyclic dimer of norbornadiene. Used is a three-component homogeneous catalytic system consisting of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride. Resulting dimer can be used as a component of high energy fuel.
摘要:
Catalytic codimerization of norbornadiene and 1,3-pentadiene yields an olefinic codimer which, after hydrogenation, has utility as a high energy missile fuel or a diluent for a higher viscous missile fuel. Used is a three-component homogeneous catalytic system, consisting of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphina ethane and an alkyl aluminum chloride.
摘要:
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.

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:
Hydrogenolysis of a saturated endo-endo dihydronorbornadiene hexacyclic dimer involves the use of a catalytic amount of a Group VIII metal and the presence of hydrogen. The resulting pentacyclic isomers can be used as a diluent for depressing the freezing point of the saturated hexacyclic dimer which is a component of a high density missile fuel.
