Water-mediated synthesis of disubstituted 5-aminopyrimidines from vinyl azides under microwave irradiation

Synthesis and Characterization of Cr2O3 Nanoparticles with Triethanolamine in Water under Microwave Irradiation

Cr2O3 nanoparticles were prepared using Cr(NO3)3.9H2O as starting material, triethanolamine (TEA) as template and water as green solvent under microwave irradiation. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), photoluminescence (PL) and Raman spectroscopy. The size distribution of individual particles we...

Efficient classical synthesis of aminoazines under microwave irradiation

In the present study, Aminoazines were prepared from the reaction of amidrazone hydroiodide with various aromatic aldehydes in the presence of a solid base under microwave irradiation with power level of 850 W for 2-7 min in high yields. The amidrazone hydroiodide can also be prepared by the reaction of S-methyl isothiobenzamide hydroiodide and hydrazine in methanol under nitrogen gas. All synt...

Synthesis of Metallophthalocyanines Under Solvent Free Conditions Using Microwave Irradiation

Phthalocyanine complexes of Cu, Co, Ni, Fe, Zn, Pd, Pt and Ru have been synthesized from reaction between phthalonitrile and proper metal salts upon exposure to microwave irradiation under solvent-free conditions and considerably reduced reaction times.

Synthesis of 2-Amino-4hydroxy-1H-Pyrrole-3-Carbonitrile from Glycine Under Microwave Irradiation

Reaction of Glycin with Malononitrile afforded respective Pyrrole. Pyrrole is one of the heterocyclic compounds with very important biological activities. Heterocycles are extremely important because of their wide range of applications that goes from their use as pharmaceuticals and agrochemicals to dyestuffs and additives. In this view, it was proposed to synthesize pyrrole-3-carbonitrile deri...
