The synthetic investigation of 7-methoxybenzofuranyl-carbamates (7-Methoxy-benzofuran-2-yl)-carbamic acid Et ester and I (R1 = C6H5, 4-ClC6H4, 2-ClC6H4, etc.) and carbamides II (R2 = C6H5, 4-ClC6H4, cyclohexyl, etc.) via the Curtius rearrangement of 7-methoxybenzofuran-2-carbonylazide has been reported. The required intermediate carbonyl azide was synthesized from ethyl-7-methoxybenzofuran-2-carboxylate by two established synthetic routes: (1) 7-methoxy-benzofuran-2-carboxylic acid and 7-methoxy-benzofuran-2-carbonyl chloride and (2) 7-methoxy-benzofuran-2-carboxylic acid hydrazide. The carbonyl azide was subjected to Curtius rearrangement in anhydrous medium with ethanol and various aromatic phenols to obtain carbamates (7-methoxy-benzofuran-2-yl)-carbamic acid Et ester and I while with primary amines and cyclohexylamine to obtain carbamides II. The structures of all the synthesized compounds I and II were confirmed by their IR, 1HNMR and mass spectral data. All the newly synthesized compounds I and II were screened for anti bacterial activity and antifungal activity. Few selected compounds were screened for their anti oxidant properties and DNA cleavage studies. Few compounds exhibited appreciable activity.

Computed Properties of C7H7BrOIn 2022 ,《Metal-organic framework grown in situ on chitosan microspheres as robust host of palladium for heterogeneous catalysis: Suzuki reaction and the p-nitrophenol reduction》 was published in International Journal of Biological Macromolecules. The article was written by Wang, Gongshu; Wang, Jiwei; Chen, Zhangpei; Hu, Jianshe. The article contains the following contents:

In this study, the metal-organic framework ZIF-8 has been successfully planted on the surface of chitosan microspheres (CS/PDA@ZIF-8) using polydopamine as connecting material for the first time, which avoids the use of expensive, non-renewable, and non-biodegradable polystyrene microspheres commonly used as templates to prepare core-shell structures. Moreover, the metal-organic framework ZIF-8 was prepared specially by three different methods and all characterized by SEM, TEM, and BET, and the ZIF-8 shell prepared at room temperature presents a regular morphol., uniform size, large sp. surface area (353.1 m2/g) than the shells prepared by the other methods including. The CS/PDA@ZIF-825@Pd with high catalytic activity and high stability was especially prepared by encapsulating Pd nanoparticles into the pores of CS/PDA@ZIF-825. Notably, the fabricated catalyst performed well in an array of reactions, for example the Kapp value of the p-nitrophenol reduction reaction reached 0.0426 s-1, and the TOF of the Suzuki coupling reaction reached 128 h-1. In addition, the ZIF-67, UiO-66, UiO-66-NH2, HKUST-1, and NH2-MIL-53(Al) were also grown on chitosan microcapsules successively to prepare the core-shell microspheres, which prove the universal applicability of this strategy. And beyond that, the introduction of chitosan microspheres endows the material with biodegradable properties and excellent recycling properties.

《Stereoselective synthesis of trifluoromethyl-substituted 2H-furan-amines from enaminones》 was published in Chemical Communications (Cambridge, United Kingdom) in 2020. These research results belong to Liang, Xiaoyu; Guo, Pan; Yang, Wenjie; Li, Meng; Jiang, Chengzhou; Sun, Wangbin; Loh, Teck-Peng; Jiang, Yaojia. Recommanded Product: N,N-Dimethylformamide Dimethyl Acetal The article mentions the following:

A straightforward strategy for synthesis of highly functionalized trifluoromethyl 2H-furans was described. The copper catalyzed method relies on a cascade cyclic reaction between enaminones and N-tosylhydrazones. This method allowed the synthesis of 2-amino-3-trifluoromethyl-substituted 2H-furan derivatives carrying a quaternary stereogenic center as single diastereomers. The proposed reaction mechanism involved an amino-cyclopropane intermediate formed in the cyclopropanation of enaminones. The developed method tolerated a broad spectrum of functionalities and the obtained 2H-furan derivatives were useful synthetic intermediates for preparing other trifluoromethyl-substituted compounds The experimental process involved the reaction of N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5Recommanded Product: N,N-Dimethylformamide Dimethyl Acetal)

Gao, Wei-Jie; Yu, Hui-Juan; Chen, Jian; Xiao, Jing; Fang, Jing-Kun; Jia, Xiang-Rui; Peng, Chi-Fang; Shao, Guang; Kuang, Dai-Bin published their research in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021. The article was titled 《Simple hole-transporting materials containing twin-carbazole moiety and unconjugated flexible linker for efficient and stable perovskite solar cells》.Product Details of 101-70-2 The article contains the following contents:

Three twin-carbazole-based hole-transporting materials (HTMs) bearing an unconjugated flexible linker and four peripheral diphenylamine groups with different methoxy positions (pp-, pm-, and po-) are first synthesized (GJ-pp, GJ-pm, and GJ-po) and successfully employed in perovskite solar cells (PSCs). The HTMs were obtained from simple synthetic steps and facile purification techniques. The thermal stability, optical and electrochem. properties, d. functional theory calculations, hole-transporting properties, X-ray diffraction, hole transfer dynamics, hydrophobic properties, surface morphol., and photovoltaic performances were measured and discussed. Device performance depends on the methoxy group positions. GJ-pp shows the best power conversion efficiency (17.23%) among the three twin-carbazole-based HTMs, and slightly lower than that of the spiro-OMeTAD-based devices (17.96%). However, the GJ-pp-based devices show outstanding thermal stability compared with the spiro-OMeTAD-based ones. Laboratory synthetic cost of GJ-pp is merely 29.0% of the purchasable spiro-OMeTAD price, and the concentration of GJ-pp is lower than that of spiro-OMeTAD (50.0 vs. 72.3 mg mL-1). The results demonstrate that the twin-carbazole moiety can endow enhanced charge transport properties due to its potential intermol. interactions, and the conjugated core is unnecessary for promising HTMs. In the part of experimental materials, we found many familiar compounds, such as Bis(4-methoxyphenyl)amine(cas: 101-70-2Product Details of 101-70-2)
