A new graphene oxide (GO) supported Cu(II) Schiff base complex (GO-SB-Cu) was synthesized by utilizing Schiff base functionalized GO (GO-SB) and copper acetate in ethanol under reflux. The synthesized complex was characterized using several techniques such as fourier transform IR spectroscopy (FTIR), powd. X-ray diffraction (PXRD), fourier transform (FT-Raman), thermo gravimetric anal. (TGA), field emission SEM (FESEM), high resolution transition electron microscopy (HRTEM), elemental dispersive X-ray anal. (EDX), elemental mapping, X-ray photo electron spectroscopy (XPS) and at. absorption spectroscopy (AAS) anal. The complex was found to be highly efficient in the click reaction for synthesis of 1,4-disubstituted 1,2,3-triazoles at room temperature and an operationally simple and efficient one-pot synthesis of 2H-indazoles from com. accessible reactants at ambient temperature, without using any base, additive or co-catalyst. A variety of electron donating/withdrawing groups were employed to explore the scope of the reactions. Interestingly, aliphatic and heterocyclic amines were also tested and found active in the synthesis of 2H-indazoles. The results demonstrated that the reaction could be scaled up conveniently and the catalyst could be easily recycled up to successive four times without any noteworthy loss in the catalytic action. High yield of the products, easy workup, environmentally benign, high stability of the catalyst and mild reaction conditions are the key points of this catalyst. All the synthesized organic products were identified by 1H and 13C NMR spectroscopy. In addition to this study using o-Bromobenzaldehyde, there are many other studies that have used o-Bromobenzaldehyde(cas: 6630-33-7Related Products of 6630-33-7) was used in this study.
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Related Products of 6630-33-7Synthetic 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.
