Synthetic Route of 3889-13-2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 3889-13-2, Name is 5-Nitro-2,3-dihydro-1,3-benzoxazol-2-one, molecular formula is C7H4N2O4.

Synthesis of 4-(2-hydroxyphenyl)-1-phenyl-1,2,4-triazolidine-3,5-dione derivatives through cyclic transformations of 3-(2-phenylcarbazoyl)-2(3H)-benzoxazolone derivatives
Four 3-(3-benzylidene-2-phenylcarbazoyl)-2(3H)-benzoxazolone derivatives 3 have been synthesized from benzoxazolone derivatives 1 and benzaldehyde N-chloroformylphenylhydrazone 2. By acid hydrolysis, these compounds yielded 3-(2-phenylcarbazoyl)-2(3H)benzoxazolone derivatives 4 which were not isolated and were transformed via an intramolecular reaction into 4-(2-hydroxyphenyl)-1-phenyl-1,2,4-triazolidine-3,5-dione derivatives 5 in a good yield. Attempts to cyclize these compounds by intramolecular elimination of water into tricyclic compounds 6 with various dehydrating agents were unsuccessful.
