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 اولA hybrid density functional theory (DFT) and ab initio study of α-Acyloxycarboxamides Derived from Indane-1, 2, 3-trione
α-acyloxycarboxamides are synthesized from three component Passerini reaction between indane-1,2,3-trione, isocyanides, and thiophenecarboxylic acids in quantitative yields. The structures of the final products were confirmed by IR, 1H and 13C NMR spectroscopy, mass spectrometry, and elemental analysis. The B3LYP/HF calculations for computation of 1H an...
متن کاملOrganocatalytic decarboxylative aldol reaction of β-ketoacids with α-ketophosphonates en route to the enantioselective synthesis of tertiary α-hydroxyphosphonates.
The first example of an asymmetric organocatalyzed decarboxylative aldol reaction of β-ketoacids (aroylacetic acids) with α-ketophosphonates that produces a quaternary chiral centre has been developed. A quinidine based bifunctional urea derivative was identified as the preferred catalyst affording γ-aroyl tertiary α-hydroxyphosphonates in good yield and enantioselectivity. The 31P NMR spectros...
متن کاملSynthesis and Characterization of α-Fe2O3 Nanoparticles by Microwave Method
α-Fe2O3 (hematite) is the most stable iron oxide under ambient conditions. This transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. In this report, a novel microwave method for preparation of α-Fe2O3 nanoparticles has been developed. The process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...
متن کاملTHE SYNTHESIS AND ANTIMICROBIAL PROPERTIES OF 4-CHLORO-2,6-BIS (2-HYDROXY- α- TOLYL) PHENOL
The synthesis of the title compound is described. This compound was found to be active (3c) against a number of pathogenic microorganisms in vitro. It is a non-absorbable antibacterial topically and its pharmacologic studies revealed that it is a non-toxic agent with a wide range of safety. It proved to be effective in the prevention and treatment of pseudomonaswound infections in voluntee...
