The reaction of ethyl (Z)-N-(2-amino-1,2-dicyanovinyl)formimidate with hydrazine monohydrate leads to (Z)-N3-(2-amino-1,2-dicyanovinyl)formamidrazone in almost quantitative yield. This compound proved to be an important starting material for the synthesis of the corresponding N1-isopropylidene-and N1-acetyl-formamidrazones.
(Z)-N-(2-氨基-1,2-二氰基乙烯基)甲酰亚胺乙酯与一水合肼的反应以几乎定量的产率得到(Z)-N 3-(2-氨基-1,2-二氰基乙烯基)甲酰胺ami。 。该化合物被证明是用于合成相应的N 1-异亚丙基-和N 1-乙酰基-甲酰胺基的重要起始原料。
