Sažetak
1, 3, 5-Trihydroxy-1, 3, 5-triazine-2, 4, 6(1H, 3H, 5H)-trione (5), the trimer of hypothetical acid HO-N=CO, was synthesized by hydogenolysis of 1, 3, 5-tribenzyloxy-1, 3, 5-triazine-2, 4, 6-(1H, 3H, 5H)-trione (4). Similarly, the 1-(N-hydoxycarbamoyl)benzotriazole (6), as solid HONCO donor, was prepared by hydogenolysis of its benzyl derivatives 2. Compound 4 was obained by trimerization of intermediary N-benzyloxyisocyanate (3) which liberates in the thermal dissociation of 1-(N-benzyloxycarbamoyl)benzotriazole (2). In the reaction with 2-phenylethylamine, compund 6 gave N-hydroxy-N'-(2-phenylethyl)urea (7).
