Aromaticity of substituted fulvene derivatives: substituent-dependent ring currents.
Fulvene is a non-aromatic molecule, but variation of the electron-donating/withdrawing power of substituents exo to the five-membered ring can drive the system between the extremes of aromatic and antiaromatic, as judged by prediction of fully developed diatropic and paratropic ring currents through ab initio calculations made at the ipsocentric 6-31G**/CTOCD-DZ CHF level.
متن کاملSynthesis and antibacterial activity of the 4-quinolone-3-carboxylic acid derivatives having a trifluoromethyl group as a novel N-1 substituent.
Novel 1-trifluoromethyl-4-quinolone derivatives (8a,b) were synthesized, and the antibacterial activity of each was evaluated. An oxidative desulfurization-fluorination reaction was employed to introduce a trifluoromethyl group at the N-1 position as a key step. Among the derivatives, 8a was found to exhibit antibacterial activity comparable to that of norfloxacin (1) against Staphylococcus aur...
متن کاملSaccharomyces Cerevisiae as a Biocatalyst for Different Carbonyl Group under Green Condition
In this researchsaccharomyces cerevisiae (baker’s yeast) was used as a cheap, readily accessible, selective, efficient, and green bio-catalyst in a chemo selective reduction of carbonyl group to hydroxyl group. In this green procedure three substrates e.g. (3-(3-nitrophenyl)aziridin-2-yl)-1-phenyl-methanone, pyruvate ester, and 2-acetyl-γ-butyrolactone were r...
متن کاملtranslating allusive devices:a survey of a portrait of the artist as a young man by james joyce
تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
15 صفحه اول"Substituent on benzenesulfonyl group" effect in use of 8-benzenesulfonamidoquinoline derivatives as chelate extractant.
"Substituent on benzenesulfonyl group" effect of 8-benzenesulfonamidoquinoline [N-(8-quinolyl)benzenesulfonamide, Hbsq] as bidentate chelate extractant for divalent metal cations was investigated with using Hbsq and its eight derivatives. Introduction of electron-withdrawing substituent on the benzenesulfonyl group in Hbsq enhanced the extractability that originated from its inductive effect. F...
