Abstract
1,1-Diamino-2-nitroethylenes reacted with dimethyl acetylenedicarboxylate (2) to give an electrophilic adduct (dimethyl 2-[(2-imidazolidinylidene)nitromethyl]-2-butenedioate) as well as cyclocondensation products derived from the electrophilic adducts. The reaction of 1,1-dimorpholino-2-nitroethylene with 2 afforded dimethyl 2-(2,2-dimorpholino-1-nitroethenyl)-2-butenedioate or dimethyl 2-(dimorpholinomethylene)-3-(nitroethylene)butanedioate derived from the [2+2] cycloadduct.
