در بخش اول ، تهیه و شناسایی کربن نانو تیوب عامل دار شده توسط فسفونیک اسید (mwcnts-c-po3h2) و کاربرد آن به عنوان کاتالیست مناسب، هتروژن و قابل بازیافت در سنتز ترکیبات آلی مورد مطالعه قرار گرفت. ما مشاهده کردیم که این کاتالیست به عنوان یک کاتالیست مناسب،هتروژن و قابل بازیابی در واکنشهای زیر عمل میکند: آسیلاسیون الکلها، فنولها، تیولها و آمینهای آروماتیک تهیه مشتقات کوئین اکسالین تهیه مشتقات 1،1...
The present study describes synthesis of a series of 2-phenyl benzimidazole-1-acetamide derivatives and their evaluation for anthelmintic activity using Indian adult earthworms, Pheretima posthuma. The structure of the title compounds was elucidated by elemental analysis and spectral data. The compounds 4-({[2-(4-nitrophenyl)-1H-benzimidazol-1-yl]acetyl}amino) benzoic acid (3a), N-ethyl-2-[2-(4...
A new chromophore, 2-(4-nitrophenyl)-1H-indole (NPI), was synthesized as a potential photolabile protecting group. Caged benzoic acids featuring the NPI chromophore were model compounds. Benzoic acid released in moderate yields (~ 40–60%) upon photolysis of caged without any additional chemical reagents. Interestingly, an aldehyde, 1-(5-(1-formyl-1H-indol-2-yl)-2-nitrophenyl)ethyl benzoate, iso...
