Benign approaches for the microwave-assisted synthesis of quinoxalines

Aqua mediated SnO2 nanoparticles: A recyclable and benign catalyst for the synthesis of Quinoxalines

An efficient and mild synthesis of quinoxalines in cludingcyclo-condensation of 1, 2-phenylenediamine and 1, 2-diketonesin the presence of1mol% catalytic amount of SnO2 nanoparticles (1 mol%) in water at room temperature is established. On the whole, this study introduced at this point is substantial in terms of using water as solvent, low reaction time (5 to 10 minutes), high yields...

Microwave-assisted synthesis of molybdenum oxide nanoparticles

This paper focused on a simple approach for synthesis of molybdenum oxide (MoO3) nanoparticles and reports a facile route for synthesis of such nanoparticles, using microwave irradiation as a homogenous and powerful source of heating, using ethylene glycol as the solvent and heating medium. For more investigations, besides microwave heating, the obtained solutions were also treated by conventio...

Microwave Assisted Synthesis of Nano Zeolite Seed for Synthesis Membrane and Investigation of its Permeation Properties for H2 Separation

MFI-type zeolite membranes (ZSM-5) were prepared on α-alumina tubular supports and tested for separation of H2/CO mixtures. The effect of pressure and temperature on H2 and CO flows and selectivity was investigated. The best results in this work were obtained with a ZSM-5 membrane prepared over a porous α-alumina tube seeded with zeolite nanocrystals synthesized with m...

Microwave Assisted Synthesis of N-Benzylenaminones Catalyzed by Chloroacetic acid

Benzylaminoalkenones and benzylaminoalkenoates 3 were synthesized from reaction of benzylamine with corresponding 1,3-diketones and 1,3-ketoesters in the presence of catalytic amount of chloroacetic acid under microwave radiation. This method offers several advantages including high yield of products, recyclable of the catalyst and easy experimental work-up procedure.
