A new method for the oxidation of 4-phenylurazole to 4-phenyltriazolinedione

A new method for the oxidation of 4-phenylurazole to 4-phenyltriazolinedione. Mallakpour, Shadpour E. (Coll. Chem. 10544-72-6 and 15988-11-1 are also occured in this study., Isfahan Univ. Technol., Isfahan, Iran). J. Chem. Educ., 69(3), 238-41 (English) 1992. CODEN: JCEDA8. ISSN: 0021-9584. DOCUMENT TYPE: Journal CA Section: 20 (History, Education, and Documentation) Section cross-reference(s): 38 A lab. expt. is described in the synthesis of 4-phenylurazole from Et carbazate and then the oxidn. of the urazole with NO2-N2O4 to yield 4-phenyl-1,2,4-triazoline-3,5-diene. The author warns that the gaseous NO2-N2O4 is highly toxic and the phenylisocyanate used in the expt. is a lacrimator. Thus, all operations involving these compds. must be conducted in an efficient hood. .

Nitrogenous heteroconjugates

Nitrogenous heteroconjugates. VII. Reactions of 4-phenyl-1,2,4-triazline-3,5-dione. Seoane, C. 15988-11-1 are also occured in this study.; Soto, J. L. (Fac. Quim., Univ. Complutense, Madrid, Spain). An. Quim., 73(9-10), 1210-11 (Spanish) 1977. CODEN: ANQUBU. ISSN: 0365-4990. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Adducts I (R = R1 = H, Me; R = Me, R1 = H) were obtained in 17-30% yield by treating 4-phenylurazole with phenylenedibenzamides II in the presence of Pb(OAc)4. The reaction failed with o-(4-MeC6H4SO2NH)2C6H4. .
