Synthesis of some Novel Metal Complexes of 4-Hydroxy Benzopyran-2-Ones as Antimicrobial Agent
Complexes of 3-[{3-(3'-bromo phenyl)}-prop-2-enoyl]-4-hydroxy-6-methyl-2H-chromen-2-one with Cu(II), Ni(II), Fe(II), Co(II) and Mn(II) have been synthesized and characterized using elemental analysis, IR spectra and conductivity measurements. These studies revealed that they are having octahedral geometry of the type [ML2 (H2O)2]. In-vitro antimicrobial activity of all synthesized compounds and...

در این تحقیق، ابتدا از واکنش 5-برمو-2-کلرو-6- متیل-4-پیریمیدین آمین (1) با هیدرازین هیدرات در حلال اتانول، 5-برومو-2-هیدرازینو -6-متیل -4-پیریمیدین آمین (2) به دست آمد. سپس از واکنش این ترکیب با تری اتیل اورتو استر های مختلف در حلال استیک اسید محصولات تری آزولوپیریمیدین (a,b3) حاصل گردید. همچنین از واکنش مشتق هیدرازین دار (2) با سدیم نیتریت در حلال استیک اسید و آب حد واسطی ایجاد شده است که از ر...
15 صفحه اولcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولIsomerization of linear to angular [3]phenylene and PAHs under flash vacuum pyrolysis conditions.
[structure: see text]. Flash vacuum pyrolysis (FVP) of linear [3]phenylene affords its angular counterpart and the same mixture of polycyclic aromatic hydrocarbon isomers as that observed on FVP of angular [3]phenylene. A mechanism, supported by a 13C labeling study, is proposed to explain these results.
متن کاملReactions of 2-(pyrrol-1-yl)benzyl radicals and related species under flash vacuum pyrolysis conditions.
2-(Pyrrol-1-yl)phenoxyl, aminyl, thiophenoxyl and benzyl radicals 2a-2d, respectively, were generated in the gas-phase under flash vacuum pyrolysis conditions. In all cases except the phenoxyl, cyclisation took place providing acceptable synthetic routes to the fused heterocycles 11, 14 and 15, respectively. Only sigmatropic rearrangement products were isolated, in low yields, from the phenoxyl...
