Microwave-Assisted Synthesis of Novel Functionalized Ketenimines and Azadienes via a Solvent-Free Reaction of Isatoic Anhydride, Alkyl-Isocyanides and Dialkyl Acetylenedicarboxylates

Ketenimines and azadienes are transient intermediates in organic chemistry especially in elimination-addition processes and in the formation of heterocyclic systems. These compounds play a considerable role as intermediates in the synthesis of heterocyclic ring systems. In this present research synthesis of novel ketenimines and azadienes via multicomponent reactions (MCRs...

Microwave-Assisted Synthesis of Alumina Nanoparticles Using Some Plants Extracts

In present study we used five green plants for microwave assisted synthesis of Alumina nanoparticles from Aluminum nitrate. Structural characterization was studied using x-ray diffraction that showed semi- crystalline and possibly, amorphous structure. Fourier infrared spectroscopy was used to determine Al-O bond and functional groups responsible for synthesis of nanoparticles. FTIR confirmed e...

Microwave–Assisted Hydrothermal Synthesis and Optical Characterization of SnO2 Nanoparticles

Semiconductor nanoparticles exhibit size dependent properties due to quantum confinement effect that are not present in their bulk counterparts. In this work, extremely fine and pure SnO2 nanoparticles of ~1.1 nm size were synthesized by a solution process, in which amorphous precipitate of SnO2 was crystallized by microwave heating. The particles sizes varied from ~1.1 to ~2.7 nm. By XRD analy...

One Step Rapid Synthesis of Nano-Crystalline ZnO by Microwave-Assisted Solution Combustion Method

In this study nano-crystalline ZnO particles were synthesized by microwave-assisted solution combustion method. Zinc nitrate and urea were used as oxidizer and fuel, respectively. The effect of fuel to oxidizer (F/O) ratio on ZnO powder properties was investigated by using different urea/nitrate ratios. X-ray diffractometer, scanning electron microscopy and fourier transform infra-red were used...
