Preparation and characterization of a novel DABCO based tetra cationic ionic liquid as a reusable catalyst for the multi-component synthesis of 2H-indazolo[2,1-b]phthalazine-trione and [1,2,4]triazoloquinazolinone derivatives under solvent-free condition

In current study, a new DABCO based tetra cationic ionic liquid, formulated as [C4(H-DABCO)2][HSO4]4 is easily prepared and characterized using FT-IR, 1H NMR,13C 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.
