摘要:
N,N'-[Oxy(or methylene)di-p-phenylene]bis(4,10,11,12-tetrachlorodecahydro-1H-4,10-etheno[2]-benzofuro[5,6-f]isoindole-1,3,6,8-tetraones) were synthesized by the Diels-Alder reaction of N,N'-[oxy(or methylene)di-p-phenylene]bis(endo,exo-7,8,9,10-tetrachlorobicyclo[4.4.0]deca-7,9-diene-3,4-dicarboximide) with maleic anhydride, and stereochemical structure of the products was studied.
