An Easy Access to Hydrazinocarbonyl Carbamic Acid Ethyl Esters

Faleschini, Gottfried

, p. 327 - 331 (1999)

The reaction of carboisocyanatidic acid ethyl ester with hydrazines and 3,5-dioxo-1,2,4-triazolidine is reported. The thermal cyclization of the products to 1-substituted 3,5-dioxo-1,2,4-triazolidines and to [1,2,4]triazolo[1,2-a][1,2,4]triazole-1,3,5,7-tetraone was investigated.
