Sy nthesis of nanoparticles silica sulfuric acid (NPs SiO۲-OSO ۳H): a so lid phase acidic cat alyst for s ynthesis of biscoumarin deriv atives

In the last few years, literature has highlighted the im portance of nanosized materials in several scientific and technological areas , and many research co uncils have intensified investments in nanotechnolo gy for the coming years [۱].Coum arins play an important role in both natural and s ynthetic or ganic che mistry because of their potential applications in fragrance, pharmaceutical and agroch emical indu stries [۲]. We have now used nanoparticle silica sul furic acid (NPs SiO۲-OSO۳H) as a new ra pid method affording excellen t yield and using solid phase acidic green catalyst for the synthesis of biscou marin derivatives at reflux in water.
