3.5- Diamino-1,2.4-triazole

Computational methods were employed to predict molecular vibrations in 3-mercato-l,2,4-triazole 18 and 3,5-diamino-1,2,4-triazole 19 in order to fully assign the Fourier transform infrared (FTIR) and FT-Raman spectra of these molecules <2004SAA709, 2005SAA261>.

The intermediate A-anilinoamidino-2-thioureas, which result from the treatment of 3,5-diimino-l,2,4-dithiazolines (thiurets) with phenyl-hydrazine, were reported by Fromm64-88 to cyclize to 3,5-diamino-1,2,4-triazoles. Kurzer and co-workers, who had earlier reported the cyclization of amidinothioureas to 1,2,4-triazoles,67 extended this work to l,3-bis(isopropylideneimino)-2-arylthiocarbamoylguanidines (35),...

Suspension polycondensation of pyromellitic dianhydride and 3,5-diamino-1,2,4-triazole yielded triazole-containing polyimide beads that were used as a support for Mo02(acac)2 [60]. The resulting catalyst showed high activity and selectivity in the epoxidation of cyclohexene and cycloctene as well as in the epoxidation of noncyclic alkenes such as styrene, 1-octene, and 1-decene with TBHP. The catalyst could be recycled 10 times and activity decreased significantly in the case of 1-octene epoxidation whereas activity remained high in the epoxidation of cyclic alkenes. 

Diamino-1,2,4-triazole is a component in polyester imide coatings with increased hardness that is used for thermosetting insulating varnishes for coating of electric wires. Acid components are terephthaUc acid esters and trimelUtic acid anhydride. 

Oxydianiline was separately mixed with 2,6-diaminopyridine and 3,5-diamino-1,2,4-triazole, to form a mixture of diamines. Then poly-(imide)s (PI)s were synthesized by reacting the mixture of the diamines and pyromellitic dianhydride. The adhesion strength of sputter-deposited copper to PI films is proportional to the content of functional groups." ...

The incorporation of pyridine or triazole improves the adhesion between poly(imide)s and copper [71]. Poly(3,3, 4,4 -benzophenone tetracarboxylic dian-hydride-3,5-diamino-1,2,4-triazole) (BTDA-DATA) contains the triazole moiety as repeating units. Poly(4,4 -oxydiphthalic anhydride-1,3-aminophen-oxybenzene-8-azaadenine) (ODPA-APB-8-AA) bears the triazole moieties at the end [72]. BTDA-DATA starts to decompose at 350 °C. However, ODPA-APB-8-AA starts to decompose at 400 °C. The polymers have been tested as adhesives for copper surfaces. The adhesion is increased by the formation of copper complexes.
