The effect of chalcogen substitution on the structure and spectroscopy of 4,7-dimethyl-2: H -chromen-2-one/thione analogues
(Royal Society of Chemistry, 2017-02)
4,7-Dimethyl-2H-chromen-2-one (1) and its novel sulfur analogue 4,7-dimethyl-2H-chromen-2-thione (2) were synthesized and fully characterized by spectroscopic methods and mass spectrometry. The crystal structure of compound ...
Light-induced relief gratings and a mechanism of metastable light-induced expansion in chalcogenide glasses
(American Physical Soc, 2001-06-01)
We report on a metastable light-induced volume expansion in Ge25+xGa10-xS65 glasses under irradiation with band gap (UV) light, which can result in recording of relief gratings on their surface in the case of irradiation ...

Síntese e aplicação de calcogenetos derivados de peptídeos em catálise assimétrica
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2010-07-12)
In the present work, we have developed a flexible, modular synthetic route for the preparation of new chiral chalcogen peptide derivatives containing sulfur,
selenium or oxygen and evaluate their application as catalysts ...
Estudo sobre a síntese e caracterização de clusters binários e ternários de organocalcogenetos contendo metais de transição
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2008-03-31)
This work presents a study related to the synthesis and characterization of a series of clusters with chacogen-metal bonds in which the metals are mercury, silver, cobalt, nickel, palladium, cadmium and zinc. The synthetic ...

Formação da ligação carbono-carbono envolvendo organocalcogênios catalisada por metais de transição
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2019-02-22)
In this thesis we developed a methodology for carbon-carbon bond formation via a cross-coupling reaction between classical nucleophiles and organoselenium electrophiles catalyzed by transition metals. The fact that ...
Structural, electronic and magnetic properties of copper(I) cubic clusters
(Elsevier Ltd, 2020-11-02)
We report the molecular and electronic structure, and the calculated electronic excitation energies, using the time dependent density functional methodologies (TD-DFT), and the induced magnetic field (Bi) of a series of ...
