synthesis of sulfides from alcohols and thiols in solvent-freeconditions and deoxygenation of sulfoxides
کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولNatural Phosphate As Solid Catalyst To Synthesis Of 1- Acetal diethyl-1H-indole-3- carbaldehyde Assisted Microwave Irradiation
An efficient method for synthesis of 1Acetal diethyl-1H-indole-3-carbaldehyde by combinaison of 1H-indole-3-carbaldehyde and bromoacetal diethyl using Natural phosphate doped with K2CO3 (NP/K2CO3) is described .The reactions promoted by microwave irradiation are advantageous in many ways because of short reaction time, and solvent free reaction conditions . Several reactions of synthetic import...
متن کاملSynthesis of novel acetal thia-cage compounds.
The synthesis of novel acetal thia-cage compounds has been accomplished by the direct substitution for the oxygen atom by the sulfur atom in the reaction of the acetal groups of oxa-cages with Lawesson reagent (LR). Reaction of the tetraoxa-cage compound 2 with LR in dichloromethane at 25 degrees C sequentially gave the monothia-, dithia-, trithia-, and tetrathia-cage compounds 3, 6, 7, and 9. ...
متن کاملReactivity of 2-acylaminoacrylates with ketene diethyl acetal; [2 + 2] cycloadditions vs. tandem condensations.
The reactivity of 2-acylaminoacrylates with ketene diethyl acetal can be modulated by means of thermal conditions to yield cyclobutanes for the preparation of protected beta-hydroxycyclobutane-alpha-amino acids, or catalytic conditions that yield cyclohexanes by tandem condensations to obtain interesting building blocks that are alternatives to Danishefsky's diene.
