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 ...
Photocatalyzed reductive fluoroalkylation of 2-acetoxyglycals towards the stereoselective synthesis of α-1-fluoroalkyl-: C -glycosyl derivatives
(Royal Society of Chemistry, 2020-11)
A benign, efficient, regio- and stereoselective protocol for the syntheses of α-1-fluoroalkyl-C-glycosyl compounds bearing CF3, C4F9, and C6F13 substituents on the anomeric carbon has been developed by a new methodology ...
Radical fluoroalkylation reactions of (hetero)arenes and sulfides under red light photocatalysis
(Royal Society of Chemistry, 2019-03)
Fluoroalkylation reactions of (hetero)aromatics have been accomplished through the low-power illumination from red LEDs (λ max = 635 nm) of commercially available perfluoroalkyl iodides R F -I and phthalocyanine zinc salt ...
From the molecule to the mole: improving heterogeneous copper catalyzed click chemistry using single molecule spectroscopy
(Royal Society of Chemistry, 2017-01)
Single molecule spectroscopy (SMS) inspired the optimization of a heterogeneous 'click' catalyst leading to enhanced yields of the Cu-catalyzed reaction of azides with terminal alkynes. Changes in SMS data after optimization ...
Chain-like uranyl-coordination polymer as a bright green light emitter for sensing and sunlight driven photocatalysis
(Royal Society of Chemistry, 2020-08)
A new uranyl-coordination polymer (UCP) has been solvothermally synthesized employing succinic acid and 1,10-phenanthroline (phen) as ligands. The obtained compound with the formula [(UO2)2(phen)(succ)0.5(OH)(O)4(μ3-O)(H2O)]·H2O ...
Visible-Light Photocatalysis with Mullite-Type Bi2(Al1- xFex)4O9: Striking the Balance between Bandgap Narrowing and Conduction Band Lowering
(American Chemical Society, 2018-09)
The rich crystal chemistry of mullite-type Bi2M4O9 (M = Fe, Al, Ga) offers multiple potential applications. In particular, the strong absorption of visible light shown by Bi2Fe4O9 has led to an influx of research on its ...

(Wiley VCH Verlag, 2020-04)
Visible-light-photocatalyzed methods employed insynthetic transformations present attractive properties such asenvironmentally friendly, safety, availability and excellent functionalgroup tolerance. In this venue, research ...
Advances on the synthesis of porous TiO2 coatings by anodic spark oxidation: photocatalytic reduction of Cr(VI)
(Elsevier Science Sa, 2017-04)
Porous TiO2 coatings were obtained by anodic oxidation in spark discharge conditions, varying the range of current density (200-3000 A m−2) and the electrolyte concentration (H2SO4; 1 and 4 M). The samples were characterized ...
Photocatalytic Reactor Modeling: Application to Advanced Oxidation Processes for Chemical Pollution Abatement
(Springer International Publishing, 2019-10)
A methodology for photocatalytic reactor modeling applied to advanced oxidation processes for chemical pollution abatement is presented herein. Three distinct reactor configurations typically employed in the field of air ...
Antibiofilm effect of mesoporous titania coatings on Pseudomonas aeruginosa biofilms
(Elsevier Science SA, 2020-01)
Activation of photocatalytic titania by ultraviolet-A (UVA) radiation has been proposed as a good approach for combating bacteria. Titania powder, in solution or immobilized on a surface, has excellent UVA-assisted killing ...
