One-pot multicomponent reaction between isatin, barbituric acid, and 6-amino-1,3-dimethyl uracil was investigated <span style="font-size: 10.0pt; ...

[ 2 ] - Efficient Synthesis and Antimicrobial Evaluation of Pyrazolopyranopyrimidines in the Presence of SBA-Pr-SO3H as a Nanoporous Acid Catalyst

A simple, efficient, and environmentally friendly method has been developed for the synthesis of a series of tricyclic fused pyrazolopyranopyrimidines via a one-pot three-component reaction of barbituric acids, aromatic aldehydes, and 3-methyl-5-pyrazolone in the presence of SBA-Pr-SO3H. SBA-15 mesoporous silica material functionalized with propyl sulfonic acid groups was used as a heterogeneou...

[ 3 ] - Modification of mesoporous silica SBA-15 with different organic molecules to gain chemical sensors: a review

The recognition of the biologically and environmentally important ions is of great interest in the field of chemical sensors in recent years. The fluorescent sensors as a powerful optical analytical technique for the detection of low level of various analytes such as anions and metal cations have been progressively developed due to the simplicity, cost effective, and selectivity for monitoring ...

[ 5 ] - تهیه و شناسایی نانومتخلخل V-SBA-16و کاربرد آن به عنوان کاتالیست در فرایند اکسایش مستقیم بنزن به فنل

در این پژوهش، کاتالیست V-SBA-16 با استفاده از ماده نانومتخلخل SBA-16 به عنوان بستر و کمپلکس وانادیم طی فرایند بازروانی تهیه شد. کاتالیست تهیه شده با استفاده از فناوری‌ های جذب و واجذب نیتروژن،پراش پرتو ایکس، پرتو ‌سنجی فرابنفش ـ مرئی و میکروسکوپ الکترونی عبوری مورد شناسایی قرار گرفت. نتیجه‌ های آنالیزها نشان داد که ساختار منظم نانومتخلخل بستر در طی فرایند تهیه کاتالیست حفظ شده و دچار فروپاش...

[ 6 ] - A Green Multicomponent One-pot Synthesis of 9, 10-Diaryl-7H-benzo[d,e]imidazo[2,1-a]isoquinolin-7-one Derivatives using Nanoporous Base Silica (SBA-Pr-NH2) as Catalyst

Organic-inorganic hybrid mesoporous materials such as amino functionalized silica (SBA-Pr-NH2) have received considerable attention due to their basic catalytic applications and adsorption functions. In this work, we investigated the efficient role of SBA-Pr-NH2 as a heterogeneous nano catalyst in the synthesis of 9,10-diaryl-7H-benzo[d,e]imidazo[2,1-a]isoquinolin-7-one derivatives. Application...
