A series of pentacyclic cageketones 2b-d having no substituent was synthesized by the photochemical [2+2]-cycloaddition reaction of corresponding tricyclic dienones 1b-d. The cageketones 2b-d underwent thermal [2+2]-cycloreversion to give dienones 1b-d. The reactivities were dependent on the length of the bridge “X”.

[4+2]-Codimerization of cyclohexa-1,3-diene, cyclopentadiene, and their methyl-substituted derivatives in the presence of H-forms of synthetic mordenite and natural clinoptilolite was studied. Application of zeolites as catalyst decreases the rate of di- and trimerization of cyclopentadiene and its methyl-substituted derivatives, increases the reaction selectivity with respect to their codimers with cyclohexa-1,3-diene and its methylsubstituted derivatives as well as 4-vinylcyclohexene. Epoxidation of the synthesized codimers with the adduct of hydrogen peroxide with urea in the presence of gadolinium- and neodymium-containing phosphorus molybdenum complexes as catalysts has been investigated, and optimal conditions for preparation of diepoxides of tricyclic dienes have been found.
