A new rapid and versatile approach using Ionic liquid/DMSO as a chemical reagent for the synthesis of fused heterocyclic compounds in a highly efficient way is described. This method offers the advantages of proceeding in neutral conditions, giving high to excellent isolated yields (83–92%) for Niementowsk. synthesis with easy work.p procedure. The inherent Bronsted acidity of ionic liquid and high polarity of both IL and DMSO resulted in a significant enhancement in the reaction rate.

An Efficient and Rapid Synthesis of 2-amino-4-arylthiazoles Employing Microwave Irradiation in Water

引用

Green and Sustainable Chemistry 2011年第2期1卷 35-38页

作者： k.shor S. Jain Jitender B. Bariwal muthu k. kathiravan Vik.s k. Rask.r Gajanan S. Wank.ede Nitin A. Londhe Satish N. Dighe 不详

A facile, high yielding green chemical synthetic protocol adaptable to the parallel synthesis of a library of potentially bioactive 2-amino-4-arylthiazoles is reported herein. The methodology involves the condensation of various aracyl bromides with N-arylthioureas under MWI using water as solvent, to yield pure products (81%-97%) in very short reaction times (1-20 min).

Single crystals of L-alanine cadmium iodide(LACI)were grown by the slow evaporation technique at room temperature.A single-crystal X-ray diffraction(SXRD)model was used to evaluate the crystal structure of the as-grown LACI *** energy dispersive X-ray(EDX)analysis and ultraviolet-visible-near infrared(UV-vis-NIR)transmittance studies were carried out,and the results reveal the presence of elements in the title *** the transmittance data,the optical bandgap as a function of photon energy was estimated,and the different optical constants were calculated.A fluorescence study was performed for the LACI *** and differential thermal analyses have also been studied to investigate the thermal property of the LACI *** efficiency of the second harmonic generation(SHG)of the title crystal was *** magnetic and electrical properties were estimated by the vibrating sample magnetometer(VSM)analysis and impedance study,respectively.
