Abstract Organic sodium-ion batteries (OSIBs) using eco-friendly organic materials as electrodes have recently received much attention. However, the practical applications of OSIBs are generally limited by inherent disadvantages electrodes, such their low conductivity, poor stability, and high solubility in electrolytes. Herein, we presented [5, 10, 15, 20-tetrathienylporphinato] M (II) (MTTP, ...

Temperature programmed desorption and infrared and X-ray absorption near-edge spectroscopies were used during adsorption and reactions of thiophene in order to probe adsorbed intermediates and catalytic structures responsible for thiophene reactions with propane or H2 on H-ZSM5 and Co/H-ZSM5. Infrared spectra showed that thiophene interacts with acidic OH groups in H-ZSM5 via hydrogen bonding a...

Natural clinoptilolite zeolite (CLP) in its original or metal ion- exchanged form (Ni2+) is a weak adsorbent for relatively large thiophene derivative molecules like benzothiophene (BT) and di-benzothiophene (DBT), due to its rather restricted micro-channel structure. A novelty of this work is that upon desilication treatments, it is possible to enhance the adsorption behavior of Ni2+-exchanged...

ABSTRACT. Benzoylacetone (1) underwent a series of multi-component reactions with aromatic aldehydes and malononitrile or ethyl cyanoacetate to produce the pyran derivatives 4a-f. The latter compounds reacted yield condensation products 5a-m. On other hand, reaction 4a-f either diazonium salts 6a-c yielded arylhydrazone 7a-i. adehydes cyclohexan-1,3-dione produced 9a-c. Compound 1 Gewald’s elem...

Weinreb amidation of ethyl 4-oxo-3,4-dihydroquinazoline-2-carboxylate with aromatic amines provides a significantly improved route to anilide-type key intermediates for the synthesis of the anticancer alkaloid, luotonin A, and new A-ring-modified derivatives thereof. This method has advantages concerning overall yield, brevity, and versatility with regard to the aromatic amine component, even i...

The present investigation focuses on thiophene derivatives of oxometal centers with low d-electron counts. Treatment of a THF slurry of ReOCl3(PPh3)2 with thienyllithium reagents afforded Li(THF),ReO(thienyl)4 where thienyl is 2-C&S, 2-MeCd-l~ 2-CsHsS (benzothienyl), and 2-ClzH7S (dibenzothienyl). In contrast to the previously reported low-valent derivatives these species are reactive toward pr...

A series of novel benzosuberone derivatives were synthesized and evaluated as antimicrobial agents by using substituted benzosuberone derivatives 1a,b as starting materials. Treatment of 1a,b with phenyl isothiocyanate in dimethylformamide was followed by treatment with cold HCl solution to afford the thioamides 4a,b, which was reacted with methyl iodide to obtain methylated products 5a,b. Cycl...

BACKGROUND Due to their structural and therapeutic diversity, thienothiophene derivatives have attracted much synthetic interest because of their reactivity and biological activity. The thieno [2,3-b] thiophene moiety has been used in the design of a novel pharmaceutical therapies. Additionally, its enaminones derivatives are versatile synthons and have a lot of synthetic applications such as N...

The rise of bacterial resistance to common clinical antibiotics is calling for alternative techniques synthesize antibacterial drugs with high biodegradability. For instance, microwave-assisted synthesis a powerful technique that accelerates organic reactions. Here, we report the 19 thiophene derivatives, five furan and two thiazole using Suzuki–Miyaura cross-coupling by microwave irradiation. ...
