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.

An efficient synthesis of arylidene acetophenones have been achieved by using the microwave heating in comparison to the conventional heating. In this work compound 1-phenyle-3-(4-droxyphenyle)-2-propen-1-one, 1-(4-chlorophenyle)-3-phenyle-2-propen-1-one, and 1-(4-chlorophenyle)-3-(4-hydroxyphenyle)-2-propen-1-one have been synthesized by the condensation reaction between aromatic aldehydes and substituted acetophenones under microwave irradiation. The compounds of aldehydes and acetophenones were used as benzaldehyde, parahydroxybenzaldehyde, acetophenone, and parachloroacetophenone. The result shows that the time taken for the reaction was reduced from the conventional 1-2 hours to 60–120 seconds. The yield of the compounds in the conventional heating was moderate while the highest yield of 90–98% was observed in MWI method. The structure of the compounds was characterized by their IR,1H-NMR spectral data.
