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.

Disubstituted oxazol-5-one and pyrazoles are known to exhibit various biological activities. Therefore, in this work, we designed pyrazole containing 2,4-disubstituted oxazol-5-one(3a-g)as a new class of antimicrobial agents. Synthesis of titled compounds was carried out by two different methods. In the first method (conventional Method A), disubstituted oxazol-5-one(3a-g)was prepared by reacting 1-phenyl-3-p-tolyl-1H-pyrazole-4-carbaldehyde(1a-g)with hippuric acid(2)and sodium acetate, in an acetic anhydride for 2.5 - 4 h. In the second method (Method B), the above reaction was carried out under microwave assistance. Compared to the conventional method, the microwave-assisted synthesis of 3,4,5-trisubstituted imidazoles demonstrate several advantages, in terms of reaction time and overall yield. All the test compounds were evaluated forin vitroantibacterial and antifungal activities. In general, compounds with electron withdrawing groups showed good antibacterial and antifungal activities. Among the compound tested, compound(3d)showed highest activity.

Influence Of Substituents

AbstractA new method for synthesis of perylene-3,4-dicarboximides (PDCIs) is reported. Modified from a literature reported synthetic method, microwave assisted heating was used to perform the reaction, which not only shortened the original reaction time, from 18 hours to 30 min, but also increased the corresponding reaction yield. A variety of PDCI derivatives were synthesized in order to correlate the influence of substituents on the reaction outcome. Moreover, the photophysical and electrochemical properties of PDCIs are characterized and reported.
