Crystal structure and Raman scattering characterization of Cu2Fe1- xCoxSnS4 chalcogenide compounds (Elsevier, 2015)This work reports the synthesis by solidestate reaction of Cu2Fe1-xCoxSnS4 solid solutions. Crystal structures of Cu2Fe0.8Co0.2SnS4 and Cu2Fe0.6Co0.4SnS4 were investigated by single crystal X-ray diffraction. Both phases ...

(MDPI AG, 2016)A small series of tetrahydroindazoles was prepared, starting from 2-acetylcyclohexanone and different hydrazines using reflux and a focused microwave reactor. Microwave irradiation (MW) favored the formation of the desired ...
-
(Royal Society of Chemistry, 2016)A microwave-assisted method for the synthesis of tetracyclic tetra-hydropyridines via an intramolecular imino-Diels-Alder reaction in water is reported. The reaction proceeds under catalyst-free conditions and shows excellent ...

(Springer, 2012)The new solid solutions AgPbSb1−xBixS3 were prepared by solid state reactions. The phases were characterized by powder X-ray diffractions (XRD), scanning electron microscopy, and thermal analysis. The XRD patterns of ...
-
(2014)The crystalline structure of spinels is extremely flexible due to the presence of several sublattices in which the cations can be distributed and localized in different crystallographic sites depending on their sizes, ...
-
(Elsevier, 2015)An efficient, green, and atom economic methodology for the stereoselective synthesis of C-2 symmetry (3R,4R)-TTFOL diester derivatives has been developed. The procedure occurs through a (2R,3R)-TADDOL dioxolane cleavage ...
-
(2016)A p-tertbutylcalix[4]arene derivative was synthesized from a reaction of the diisothiocyanate p-tertbutylcalix[4]arene, obtaining crystals that were then characterized by mass spectroscopy, Raman spectroscopy, and ...
