Flow Chemistry: From assembly to the application
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-12-17)
Over the centuries, chemical reactions have been carried out in the same way in standardized glassware. On the other hand, continuous flow reactions are gaining interest regularly and demand for the related hardware toolkit ...
Multicomponent approach to silica-grafted peptide catalysts : A 3 D continuous-flow organocatalytic system with on-line monitoring of conversion and stereo-selectivity
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2014-11-28)
The derivatization of organocatalysts with functional appendages suitable to anchor onto solid supports is usually achieved by stepwise syntheses. As an alternative to such a strategy, this work describes a one-pot approach ...
Recent advances in catalysis using transition metals-bounding organic ligands assisted by ultrasound and/or microwave
(Signpost e Journals, 2015-04)
Usually, in organic and organometallic synthesis an external conventional heat source is applied to carry out a chemical reaction at high temperature. Nonetheless, these conventional heating systems have some disadvantages ...
Conjugate additions and organocatalytic sequential reactions - new approaches to old reactions
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2016-04-01)
This thesis consists in a collection of projects wherein the focus is
the application of organocatalysts to accelerate the reactions, its primary function,
as to induce asymmetry to the synthetic targets, within a ...
Benign perfluoroalkylation of aniline derivatives through photoredox organocatalysis under visible light irradiation
(Wiley VCH Verlag, 2015-12)
In this work, we present a room- or solar-light-initiated transition-metal-free radical homolytic aromatic substitution (HAS) reaction of aniline derivatives with perfluoroalkyl moieties employing perfluoroalkyl halides ...
