ABSTRACT:
Pyrolysis of N-substituted-1-cyclohexene-1,2-dicarboximide gives N,N'-substituted-pyromellitdiimides. Pyrolysis of N-substituted-1-cyclohexene-1,2-dicarboximide in the presence of N-substituted maleimides produces N,N'-substituted-3,4,5,6-tetrahydropyromellitdiimide and the Diels-Alder dimer of N-substituted-1,3-butadiene-2,3-dicarboximide.
