Synthesis of urazoles
Recent Literature
In a simple and one-pot pathway for the preparation of 4-substituted phenyl
derivatives of triazolidindiones (urazoles), aniline derivatives were reacted with ethyl
chloroformate to give the corresponding carbamate derivatives. The subsequent
reaction with ethyl carbazide gave semicarbazides, which cyclized into triazolidindiones.
