در این تحقیق سنتز و شناسایی پیرازولو پیریدین¬ها و آرن های چند عاملی، از یک واکنش چند جزیی میان دی سیانو آلکن¬ها، هیدرازین و سیانو کیتین دی تیو استال¬ها در دمای 25 درجه سانتیگراد و حلال اتانول انجام شده است. سپس جهت گسترش دامنه تحقیقات، سنتز و شناسایی برخی هتروسیکل¬ها با استفاده از α،α- دی سیانو الفین¬ها (آریل اتیلیدن مالونونیتریل¬ها) مورد بررسی قرار گرفت. در این تحقیق، واکنش سه جزئی شا...
Recommended Citation Abeysinghe, Samangi. "Keggin-type aluminum nanoclusters: synthesis, structural characterization and environmental implications." The most amazing husband ACKNOWLEDGEMENTS It is with great respect and honor that I would like to thank my advisor, Dr. Tori Forbes for all the support and guidance rendered to me during the completion of my dissertation and providing me th...
A new structure related to previously reported structure of 12-tungstoborate Keggin-type polyoxometalate, K5[BW12O40], was synthesized and its characterization by single crystal X-ray diffraction shows the polymorph structure. Further attempts have been performed to provide three component compounds based on L-proline, lanthanoid cation and K5[BW12O40] (BW12 (II)) under hydrothermal conditions ...
Interaction of Prolin, Leucine and methylurea with inorganic cluster [(PO4)M12O36].nH2O; (M = Mo, W)
Three new inorganic-organic hybrid materials based on heteropolyoxometalates, [L-C6H14NO2]3[(PO4)Mo12O36].3H2O (1), [L-C5H10NO2]3[(PO4)W12O36].H2O (2), and [C2H7N2O]3[(PO4)W12O36]. 4H2O (3), where C6H14NO2, C5H10NO2, and C2H7N2O are protonated L-leucine, L-proline, and methylurea, respectively, have been synthesized and structurally characterized by some physico-chemical methods. Elemental anal...
Omeprazole, (6-methoxy-2-((4-methoxy-3,5-dimethylpyridin-2-yl)methylsulfinyl)-1H-benzimidazole is a well-established prescribed drug, exhibits proton pump inhibitor activity. In this work, a novel, facile, economical and selective oxidation approach using H3PW12O40 as Keggin type heteropolyacids along with H2O2 in the ...
