[ 1 ] - Electron as potential and green catalyst in the multicomponent synthesis of pyrano [2, 3-d] pyrimidine derivatives
An electroorganic reaction for the synthesis of 7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1H-pyrano[2, 3-d] pyrimidine-6-carbonitrile and ethyl-7-amino-2, 4-dioxo-5-phenyl-2,3,4,5-tetrahydro-1H-pyrano[2, 3-d] pyrimidine-6-carboxylate derivatives are described, using an electrogenerated base of the anion of malonitrile or ethylcyanoacetate. This one-pot, three-component condensation of an a...
[ 2 ] - Catalytic application of an organosuperbase denderon grafted on mesoporous SBA-15 and related palladium complex in the aerobic oxidation of alcohols
An efficient synthetic method for successful synthesis of amine denderon on SBA-15 and related Pd (II) complex has been developed. This modified mesoporous material was characterized by various techniques such as TEM, XRD, atomic absorption spectroscopy, N2 adsorption-desorption, and FT-IR. The catalytic activities of the prepared catalysts were investigated by employing aerobic oxidation of al...
[ 3 ] - Hantzsch reaction using [Mesi]Cl as a new, efficient and BAIL catalyst
In this work, the efficiency, generality and applicability of new Bronsted acidic ionic liquid (BAIL) 1-methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride {[Msei]Cl} as heterogeneous and green catalyst for organic transformations are studied. Herein, the following one-pot multi-component reactions in the presence of [Msei]Cl are investigated: (i) the synthesis of quinoxaline derivatives fr...
[ 4 ] - بررسی کارآیی حذف و سینتیک جذب کادمیوم از محیط آبی توسط ذرات نانو گرافن تیول دار شده
کادمیوم یک فلز بسیار سمی می باشد که حتی در غلظتهای پایین نیز اثرات سویی بر سلامتی انسان‌ها داشته و باید از محیط‌های آبی حذف گردد. ترکیبات حاوی کادمیوم می‌توانند سبب بروز انواع سرطان‌ها، بروز ناراحتی های تنفسی و مزمن ریوی، سبب بروز بیماری ایتای-ایتای، تخریب بافت بیضه‌ها و ساختار ویژه کلیه‌ها شود. پژوهش حاضر با هدف بررسی حذف یون کادمیوم ار محلول‌های آبی توسط نانو ذرات اکسیدگرافن تیول‌دار شده در س...
