Radical Fluoroalkylation Reactions
(American Chemical Society, 2018-08)
Recent protocols and reactions for catalytic radical perfluoroalkylations will be described. The production of perfluoroalkyl radicals (RF = CnF2n+1, n ≥ 2), which effect both addition and substitution reactions on organic ...
Photocatalytic fluoroalkylation reactions of organic compounds
(Royal Society Of Chemistry, 2015-10)
Photocatalytic methods for fluoroalkyl-radical generation provide more convenient alternatives to the classical perfluoroalkyl-radical (Rf) production through chemical initiators, such as azo or peroxide compounds or the ...
Recent progress in homogeneous light-driven hydrogen evolution using first-row transition metal catalysts
(Elsevier Science SA, 2020-03)
The rich chemistry, low cost and availability offered by first-row transition metals have inspired many researchers to focus on the design, preparation and testing of a wide plethora of efficient catalytic systems for ...
Constructing Heterocycles by Visible Light Photocatalysis
(Bentham Science Publishers, 2017-05)
Heterocycles are widely spread in natural products and in many bioactive compounds, as well as in a variety of fine chemicals. Synthesis through catalysis is always an advantageous strategy and today it is difficult to ...
Perfluoroalkylation reactions of (hetero)arenes
(Royal Society of Chemistry, 2015-07)
Perfluoroalkylation reactions of arenes have not been the subject of intense study as has been the case for the trifluoromethylation reactions of aromatics. However, the new synthetic methods proposed for achieving homolytic ...
Síntese e caracterização de complexos metálicos (CuI,CuII,CoII, PdII) derivados do ligante 2-(2-piridilselanometil)piridina
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2018-10-29)
This work presents the synthesis and characterization of eight compounds derived from a new synthesis methodology of the 2-picolyl selonopyridine linker with metals of different hardness. All the compounds had their structure ...
Tuning of metal oxides photocatalytic performance using Ag nanoparticles integration
(Elsevier, 2020)
Water contamination is increasingly an important issue in developing and under developed countries. The main cause of water contaminations are industrial dyes and toxic chemicals. Hence many technologies are being developed ...
Microwave Hydrothermal Synthesis and Photocatalytic Performance of ZnO and M:ZnO Nanostructures (M = V, Fe, Co)
(Amer Scientific Publishers, 2012-01-01)
ZnO and doped M:ZnO (M = V, Fe and Co) nanostructures were synthesized by microwave hydrothermal synthesis using a low temperature route without addition of any surfactant. The transition metal ions were successfully doped ...

Comparative study of ZnO thin films doped with transition metals (Cu and Co) for methylene blue photodegradation under visible irradiation
(MDPI AG, 2020-05)
We synthesized and characterized both Co-doped ZnO (ZnO:Co) and Cu-doped ZnO (ZnO:Cu) thin films. The catalysts’ synthesis was carried out by the sol–gel method while the doctor blade technique was used for thin film ...
