Heterogeneous hydrogenation of nitroaromatic compounds on gold catalysts: Influence of titanium substitution in MCM-41 mesoporous supports
(Elsevier Science, 2016-02)
A series of Ti-modified MCM-41 supports and their respective Au catalysts were prepared and characterized to study the effect of titanium into the support and on the characteristics of the Au surface species for heterogeneous ...
The preferred all-gauche conformations in 3-fluoro-1,2-propanediol

Lipase-catalyzed synthesis of substituted phenylacetamides: Hammett analysis and computational study of the enzymatic aminolysis
(Wiley VCH Verlag, 2014-10)
A series of hydroxy-, methoxy-, and nitrophenylacetamides was synthesized by enzyme catalysis. The 28 new products were obtained through a lipase-catalyzed two-step reaction in very good to excellent yield. In the case of ...

Estudo de formação de tris-acetal internoe espiro-carbocíclicos a partir de (R)-(–)-e espiro-carbocíclicos a partir de (R)-(–)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-11-07)
In this work we studied, initially, the formation of the internal tris-ketals derivatives from their respective 2,2-bis-propargyl cyclic ketones from catalysis by gold complexes.
The reaction conditions were studied for ...

ring by a simple and effective methodology.
Five species of thiazolidinones were synthesized by three component
condensation reaction of ...
Efeito da ligação de hidrogênio intramolecular na estabilidade conformacional de amino álcoois acíclicos 1,3-dissubstituídos por cálculos DFT, RMN e IV
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em QuímicaUTFPR, 2017-05-08)
The conformational analysis covers aspects of the determination of molecular geometric structures, relative energies of conformers and interactions that control structural stabilities. In this sense, the conformational ...
