Synthesis of Hydroxy-Substituted 4-Phenyl-1,2,4-triazoline-3,5-diones

Starting from 4-aminophenol, 4-(4-hydroxyphenyl)-1,2,4-triazoline-3,5-dione (4) and 4-(4-hydroxy-3-nitrophenyl)-1,2,4-triazoline-3,5-dione (11) are synthesized.Contrary to the base-catalyzed formation of the unsubstiuted phenyl derivative 1, the heterocycle 9 is formed by heating of 1-(ethoxycarbonyl)-4-semicarbazide (8).By treatment of 4-(4-hydroxyphenyl)urazole (9) with NO2 nitration of the aromatic ring and oxidation occur simultaneously with formation of 11.Oxidation by tert-butyl hypochlorite gives 4.First investigations on polybutadienes modified with 1, 4, 11 show the influence of the additional hydroxy group to the mechanical properties.
