TL;DR: In this article, the saturated exo-exo hexacyclic dimer of norbornadiene and nobornene is codimerized to a three-component homogeneous catalytic system consisting of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride.
Abstract: 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.

TL;DR: The title compound was prepared by the interception of 1,3-dimethylcyclopenta[l]phenanthren-2-one 2 with norbornadiene to give the Diels-Alder adduct 4 followed by flash vacuum pyrolysis as mentioned in this paper.

TL;DR: A process for the production of 6-METHYL-1,4,5,8,9,10,11,12,13,14,15,16,17,18,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,54,55,56,57,58
Abstract: A PROCESS FOR THE PRODUCTION OF 6-METHYL-1,4,5,8,9,10HEXAHYDRO-1,4-METHANONAPHTHALENE BY DIELS-ALDER REACTION OF NORBORNADIENE AND ISOPRENE IN WHICH NORBORNADIENE AND ISOPRENE ARE REACTED IN A MOLAR PROPORTION OF GREATER THAN 4:3, AND PREFERABLY NOT GREATER THAN 20:1, AND UNREACTED NORBORNADIENE, WHICH MAY, IF DESIRED, BY CONTINUOUSLY RECYCLED, AND 6-METHYL-1,4,5,8,9,10-HEXAHYDRO-1,4METHANONAPHTHALENE ARE SEPARATELY RECOVERED FROM THE MIXTURE.

TL;DR: In this article, Quadricyclane (1) was allowed to react with dichloro and difluorocarbene, and the results were discussed in terms of the frontier orbitals and compared to the results obtained with norbornadiene.
Abstract: Quadricyclane (1) was allowed to react with dichloro and difluorocarbene. Cheletropic reaction occurred in both cases affording cyclopropane and cyclobutane adducts. Dichlorocarbene, being more electrophilic, underwent predominantly 1,2 cheletropic reaction with 1 yielding the cyclobutane adduct. Difluorocarbene gave mostly the exo cyclopropane adduct via 1,4 cheletropic reaction. The results are discussed in terms of the frontier orbitals and compared to the results obtained with norbornadiene.

TL;DR: Trifluoromethylcyclopentadiene, 2-propyn-1-ol, and base can give either propynyl 5-allenyl-cyclopentadienecarboxylate, 1, or tri(2propynyl) cyclopentadienesorthocarboxyate, 2.
