Single crystalline β-Co(OH)2 nanosheets have been synthesized from a layered precursor cobalt(II) acetate hydroxide by microwave heating. The average thickness of β-Co(OH)2 nanosheets is ~10 nm, with particle sizes up to 360 nm. The layered precursor was prepared using Co(CH3COO)2·4H2O, ethylene glycol, and H2O in some cases by microwave heating. Co3O4 nanosheets have been synthesized by hydrothermal oxidation of the layered precursor cobalt(II) acetate hydroxide using H2O2.Key words: nanosheets, microwave, cobalt hydroxide, cobalt oxide.

Aim and Objective: Microwave-assisted condensation of acetophenone 1 and aromatic aldehydes 2 gave chalcone analogs 3, which were cyclized to pyrazole derivatives 6a-f via the reaction with hydrazine hydrate and oxalic acid in the presence of the catalytic amount of acetic acid in ethanol. Materials and Methods: The structural features of the synthesized compounds were characterized by melting point, FT-IR, 1H, 13C NMR and elemental analysis. Results: The antibacterial activities of the synthesized pyrazoles was evaluated against three gram-positive bacteria such as Enterococcus durans, Staphylococcus aureus, Bacillus subtilis and two gram-negative bacteria such as Escherichia coli and Salmonella typhimurium. Conclusion: All the synthesized pyrazoles showed relatively high antibacterial activity against S. aureus strain and none of them demonstrated antibacterial activity against E. coli.
