Fine nanoparticles of CuO, generated in-situ by the chem. reduction method, were immobilized on cucurbit[6]uril support to afford nanocomposite CuO@CB[6] as an air-stable green powder. The nanocomposite was fully characterized by various physicochem. techniques, such as FTIR, PXRD, XPS, FESEM, EDX, Elemental mapping, HRTEM, TGA, and ICP-AES. It has been found to be an efficient heterogeneous nanocatalyst for the synthesis of a series of 2H-indazoles I (R1 = H, Me, F; R2 = Pr, cyclohexyl, 4-methoxyphenyl, 2-pyridinyl, etc.) from aldehydes 2-Br-4-R1C6H3CHO, amines R2NH2, and sodium azide, under base- and ligand-free conditions, at a low concentration of the metal (0.2 mol%). The augmented catalytic activity of the CuO NPs is attributed to the fine size of the nanoparticles. The nanocatalyst was retrieved from the reaction mixture by simple filtration and reused up to five times with insignificant deprivation in its catalytic activity. All synthesized 2H-indazoles were isolated in good to excellent yield (55-96%) and characterized by 1H and 13C NMR studies. Three new indazoles are addnl. characterized by DEPT 135 spectroscopy and HRMS spectra. The experimental part of the paper was very detailed, including the reaction process of o-Bromobenzaldehyde(cas: 6630-33-7Recommanded Product: o-Bromobenzaldehyde)
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Recommanded Product: o-BromobenzaldehydeSynthetic applications of o-Bromobenzaldehyde include: synthesis of aza-fused polycyclic quinolines through copper-catalyzed cascade reaction, preparation of 1-substituted indazoles by CuI-catalyzed coupling with N-aryl hydrazides.
