Über 1.2.4‐Triazole, IX: Synthesen und Reaktionen von 4‐Amino‐1.2.4‐triazolonen‐(5)

Abstract: Aus Carbohydrazid und Orthocarbonsgureestem erhillt man 4-Amino-I .2.4triazolone-(5), die auch bei lgngerem Erhitzen rnit aliphatischen Carbonsauren entstehen. Nach kurzer Reaktion rnit den Carbonsauren fallen 1.5-Diacyl-carbohydrazide an, die sich in saurer Lbsung partiell zu 1-Acyl-carbohydraziden verseifen lassen. Die 1 -Acyl-und die 1.5-Diacyl-carbohydrazide werden alkalisch zu 4-Amino-1.2.4-triazolon-(5) cyclisiert . Auch No-Acyl-carbazinsiiure-Hthylester ergeben z. T. bei der Umsetzung rnit Hydrazin 4-Am… Show more

“…Triazole rings are typically planar 6%-electron partially aromatic systems, possessing an extensive chemistry (Kroger et al, 1965;Temple, 1981). 1,2,4-Triazole and its derivatives are starting materials for the synthesis of many heterocycles (Milcent & Redeuilh, 1979;Milcent & Vicart, 1983).…”

“…4-amino-1,2,4-triazol-5-one (ATO) is a good candidate for this kind of material. In 1965, Kroger et al [1] first prepared ATO using carbohydrazide. Odenthal et al [2][3][4] synthesized a series of ATO derivatives.…”
