Improved Regioselectivity in Pyrazole Formation through the Use of Fluorinated Alcohols as Solvents: Synthesis and Biological Activity of Fluorinated Tebufenpyrad Analogs
(American Chemical Society, 2008-12)
The preparation of N-methylpyrazoles is usually accomplished through reaction of a suitable 1,3-diketone with methylhydrazine in ethanol as the solvent. This strategy, however, leads to the formation of regioisomeric ...
Estudo teórico da interação de flúor em nanoestruturas de BC2N
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2011-09-09)
In this work we perform a theoretical study about fluorine adsorption in BC2N
nanostructures. The fluorine interaction with the BC2N nanostructures was studied
using only atomic fluorine on two nanotubos with different ...
The reverse fluorine Perlin-like effect and related stereoelectronic interactions

Partially fluorinated polymer networks: Surface and tribological properties
(Elsevier, 2010-10-28)
Functionalization of epoxy-based networks by the preferential surface enrichment of perfluorinated tails to achieve hydrophobic surface is described. Two series of crosslinked fluorinated epoxy-based materials containing ...
Thermodynamic analysis of uranium oxides fluorination with HF(g) and F2(g)
(Springer, 2020-06)
This paper presents a thermodynamic analysis of the fluorination of UO2(s) and UO3(s) with HF(g) and F2(g). The reaction mechanisms, intermediates and final products were analyzed using different thermodynamic calculations, ...
Synthesis, characterization and evaluation of antileishmanial activity of copper(II) with fluorinated alpha-hydroxycarboxylate ligands
(SPRINGER, 2009)
In this study, Cu(II) complexes with fluorinated ligands were produced aiming at the development of new, less toxic antileishmanial metallodrugs. Complexes of the general formula CuL(2) (L = lactate, trifluorolactate, ...
Effects of helium ion irradiation on fluorinated plasma polymers
(Elsevier B.V. Sa, 2010-06-25)
The effects of ion irradiation on fluorinated plasma polymer films are investigated using profilometry, surface contact-angle measurements, infrared reflection absorption spectroscopy (IRRAS) and X-ray photoelectron ...
