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.

Michael Type Addition

A new series of tetrahydrocarbazole coupled 1,2-diazoles 4/5/6(a–o) in moderate to excellent yield was synthesized successfully via multicomponent reaction approach by adopting Michael type-addition of hydrazines on in situ generated α,β-unsaturated ketones via aldol type strategy under synthetic microwave radiations and conventional heating. Structural confirmations of all the prepared compounds were achieved by spectroscopic techniques. The best results were achieved when equal amounts of water-acetic acid were used in microwave conditions in 4 minutes.
