Preparation and application of a novel supported 3-(3-sulfamic acid imidazolium trifluoroacetate)propyl triethoxysilane on magnetic nanoparticles as a new magnetic ionic liquid for the synthesis of triazole quinazolinones and fused pyrimidines

Supported 3-(3-sulfamic acid imidazolium trifluoroacetate)propyl triethoxysilane on magnetic nanoparticles as a novel nanocatalyst was synthesized and characterized by FT-IR, XRD, TGA, SEM, TEM and VSM techniques. The catalytic activity of the magnetic catalyst was studied through one-pot synthesis of triazole quinazolinones and fused pyrimidine derivatives via one-pot multi-component reactions under thermal conditions. This catalyst demonstrated excellent catalytic properties with high percentage in short reaction times, low cost and easily separated using an external magnet and reusable without significant loss of its catalytic efficiency.
