The kinetic behavior of a series of diimides, in which the maleimide rings are linked through various bridges, in the Diels-Alder reaction with trans,trans-1,4-diphenylbutadiene and 1,3-diphenylisobenzofuran was studied.The energies of charge transfer were determined and the electron affinities were calculated by spectrophotometry of the charge-transfer complexes between the imides and hexamethylbenzene.Although the rates of reaction of the bisimides with the investigated dienes differ by seven orders of magnitude, the general type of "diene-donor, dienophile-acceptor" reaction is preserved.
