5(6)-carboxy-rhodamine 110 isomers were rapidly synthesized by condensation of 3-aminophenol and trimellitic anhydride using microwave irradiation as heating method. after esterification of the two isomers, separation and hydrolyzation provided target products,5-carboxy-rhodamine 110 and 6-carboxy-rhodamine 110, in high yields. the results shows microwave irradiation can effectively reduce the ...

textile industries use different chemicals in indigo dyeing processes. interest in eco-friendlyprocessing in the textile industry has recently increased because of a larger awareness of environmental issues. for the case of indigo dyeing process, the reducing agent conventionally used is the - environmentally unfavourable – sodium dithionite, which will be replaced in this study with an ecologi...

BACKGROUND Eugenol, the main constituent of clove oil possesses a number of medicinal activities. To enhance the medicinal property, structural modification is required. On the other hand, bismuth nitrate pentahydrate has been established as an excellent eco-friendly nitrating agent for several classes of organic compounds. RESULTS Bismuth nitrate pentahydrate-induced nitration of eugenol has...

Co₃O₄ nanorods were prepared by a facile hydrothermal method. Eco-friendly deionized water rather than organic solvent was used as the hydrothermal media. The as-prepared Co₃O₄ nanorods are composed of many nanoparticles of 30-50 nm in diameter, forming a finger-like morphology. The Co₃O₄ electrode shows a specific capacitance of 265 F g-1 at 2 mV s-1 in a supercapacitor and delivers an initial...

An extremely efficient catalytic protocol for the synthesis of spirooxindole derivatives via a one-pot three component approach in the presence of SBA-Oxime-Zn, as a heterogeneous catalyst using water as a green solvent is reported. The catalyst exhibited excellent catalytic activity, and the proposed methodology is capable of providing the desired products in good yield and short reaction time...

In this work, a simple and economical procedure for the synthesis of spiro-4H-pyranderivatives has been found through the three-component, one-pot condensation of isatin/acenaphthequinone, malononitrile and different reagents including 1, 3-dicrbonyl compounds, naphthol and 4-hydroxycumarin under thermal and solvent-free conditions in the presence ofFe2O<su...
