The reaction of bis-(p-3,5-dioxo-1,2,4-triazolin-4-yl) methane (diphenyl methanebistriazolinedione, DPMBTAD) with monomeric cyclopentadiene, 5,5-dimethoxy-1,2,3,4-tetrachlorocyclopentadiene, hexachlorocyclopentadiene, isoprene, 1,3-cyclohexadiene, and anthracene has been investigated. These reactions occurred via [4+2] Diels-Alder cycloaddition reaction and lead to the formation of novel heterocyclic bis-adducts in quantitative yields. The reaction of DPMBTAD with monomeric cyclopentadiene, 1,3-cyclohexadiene and isoprene are extremely fast even at -10degreesC in methylene chloride solution.
