SYNTHESIS OF ADDUCT OF HEXABROMO- AND 5,5-DIMETHOXYTETRABROMO-1,3-CYCLOPENTADIENES WITH N-ARYLMALEIMIDES

The diene condensation reaction was realized between hexabromo- and 5,5,-dimethoxytetrabromo-1,3-cyclopentadienes and N-arylmaleimides.It was shown that the reaction is strictly stereospecific with the formation of the endo adducts.

FACTORS DETERMINING THE REACTIVITY OF HEXABROMO- AND 5,5-DIMETHOXYTETRABROMO-1,3-CYCLOPENTADIENES IN THE DIENE SYNTHESIS WITH N-ARYLMALEIMIDES AND 4-PHENYL-1,2,4-TRIAZOLINE-3,5-DIONE

The reactivity of hexabromo-1,3-cyclopentadiene and 5,5-dimethoxytetrabromo-1,3-cyclopentadiene in diene synthesis reactions with N-arylmaleimides and 4-phenyl-1,2,4-triazoline-3,5-dione was investigated.It was shown that hexabromo-1,3-cyclopentadiene acts as diene-acceptor while 5,5-dimethoxytetrabromo-1,3-cyclopentadiene acts as diene-donor in these reactions.It is suggested that in the investigated reaction series the reactivity of the addends depends not only on their donor-acceptor characteristics but also on the localization energy.
