The adducts from the diene condensation of hexabromo- and 5,5-dimethoxytetrabromo-1,3-cyclopentadienes with bismaleimides were obtained and characterized. The reactivity of hexabromo- and 5,5-dimethoxytetrabromo-1,3-cyclopentadienes in the diene synthesis reactions with bismaleimides and with the monoadducts 1,4,5,6,7,7-hexabromo- and 1,4,5,6-tetrabromo-7,7-dimethoxybicyclo-(2.2.1)-hept-5-ene-2,3-dicarboximides was studied. In these reactions hexabromo-1,3-cyclopentadiene acts as diene-acceptor, while 5,5-dimethoxytetrabromo-1,3-cyclopentadiene acts as diene-donor. It is suggested that the reactivity of the addends in the investigated reaction series depends not only on their donor-acceptor characteristics but also on the localization energy. The IR spectra of the adducts were recorded in Vaseline oil on a UR-20 spectrophotometer. The PMR spectra were measured on a Tesla BS-487B instrument at 80 MHz with DMFA-d/sub 7/ as solvent and TMS as internal standard.
