describes a novel method for the synthesis of 1,2,4‐triazines. Firstly, isonitrosoacetophenone, p‐methylisonitrosoacetophenone, and isonitroso‐1‐acetylnaphthalene were synthesized from the reaction of butylnitrite with acetophenone, p‐methylisonitrosoacetophenone, and 1‐acetylnaphthalene, respectively. Then, symmetric derivatives of 1,2,4‐triazines were prepared from the condensation reaction of keto
这项研究描述了一种合成1,2,4-三嗪的新方法。首先,isonitrosoacetophenone,p -methylisonitrosoacetophenone,和肟基-1-环丁酮是从丁腈与苯乙酮,反应,合成p -methylisonitrosoacetophenone和1-环丁酮,分别。然后,由酮肟与对苯二hydr的缩合反应制备1,2,4-三嗪的对称衍生物。然而,在丙酮醛-1肟(酮肟)与对苯二hydr的缩合反应中未观察到杂芳族封闭。所得产物的结构通过FTIR,1 H-NMR和元素分析技术确认。
