synthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولSynthesis and estimations of antimicrobial properties of novel pyrazoline derivatives
Chalcones are the condensation product of acetophenone in combination with aromatic aldehydes in the presence of strong base. Chalcones and their metal complexes having prominent role in modern coordination chemistry. These compounds possessing novel structural features, interesting spectral and magnetic properties, have been the subject of intensive research due to their importance in medical,...
متن کاملHighly brominated anthracenes as precursors for the convenient synthesis of 2,9,10-trisubstituted anthracene derivatives
When 9,10-dibromoanthracene was treated with bromine in CCl(4) without a catalyst, 1,2,3,4,9,10-hexabromo-1,2,3,4-tetrahydroanthracene (3) was obtained in 95% yield in the absence of other stereoisomers or rearomatization products. We investigated the base-induced elimination reaction of hexabromide 3 under various conditions. Pyridine-induced elimination of hexabromide 3 afforded 2,9,10-tribro...
متن کامل-Fe2O3@SiO2-PW12 nanoparticles: Highly efficient catalysts for the synthesis of pyrazoline derivatives
A new type of magnetically-recoverable catalyst was synthesized by the immobilization of H3PW12O40 on the surface of silica-encapsulated -Fe2O3 nanoparticles. A series of novel 1,3,5-triaryl pyrazoline derivatives has been synthesized by the reaction of chalcone and phenylhydrazine in the presence of the -Fe2O3@SiO2-PW12nanoparticles, in high yields. The structures of compounds obtained were...
