Introduction of a novel nano sized n-sulfonated br?nsted acidic homogeneous catalyst for the promotion of the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-Triones

In this research work, 4,4-(butane-1,4-diyl)bis(1-sulfo-1,4-diazabicyclo[2.2.2]octane-1,4-diium) tetrachloride (NS-C4(DABCO-SO3H)2 ·4Cl) as a new nano-sized N-sulfonic acid was prepared and characterized using different types of spectroscopic methods incl

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.
