Substituted carbohydrazides 1a - e reacted with ethenetetracarbonitrile (2) in dimethylformamide with formation of diacylhydrazines 4a - e and 5-amino-1-substiuted pyrazole-3,3,4-tricarbonitriles 5a - e. On the other hand, 1a-c reacted with diethyl (E)-2,3-dicyanobutenedioate (3) to give oxadiazinone and pyrazolone derivatives 12a - e and 13a - e, respectively.
