Abstract :In this work, the synthesis of thiosemicarbazones insert ignore into journalissuearticles values(I-V); was carried out using one pot method, multicomponent and catalyst-free reaction of cyclohexyl isothiocyanate, hydrazine monohydrate and 5-substituted-2-furancarbaldehydes in good yields. The chemical structures of 5-substituted-2-furancarbaldehyde thiosemicarbazones were eludicated using UV‐Vis, IR, 1H NMR, 13C NMR, mass spectra, and elemental analysis. Also, the reaction of NiCl2.6H2O with thiosemicarbazones in 1:2 molar ratio by refluxing gave the nickel insert ignore into journalissuearticles values(II); complexes insert ignore into journalissuearticles values(Ia-Va); as binuclear and their structures characterized by UV-Vis, IR, and elemental analysis.
