Recently I am researching about ONE-POT SYNTHESIS; EFFICIENT CATALYST; SULFURIC-ACID; SOLID ACID; 3-COMPONENT; GREEN; BENZIMIDAZOQUINAZOLINONE; PHTHALAZINE; SULFATE; SYSTEMS, Saw an article supported by the University of Guilan Research Council. Category: Triazoles. Published in ELSEVIER in AMSTERDAM ,Authors: Safari, N; Shirini, F; Tajik, H. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine
In current study, a new DABCO based tetra cationic ionic liquid, formulated as [C-4(H-DABCO)(2)][HSO4](4) is easily prepared and characterized using FT-IR, H-1 NMR,C-13 NMR, TGA, and DTG analysis, and also pH-metric titration method. In continue, the efficiency of the prepared catalyst in the acceleration of the synthesis of 2H-indazolo[2,1-b]phthalazine-trione and [1,2,4]triazoloquinazolinone derivatives, is investigated. Simple experimental procedure, using available and low-cost starting materials for the preparation of the catalyst, reusability of the catalyst, isolation of products without using chromatographic methods, short reaction times, high isolated yields, and solvent-free conditions are the most important features of the present method.
