(American Chemical Society, 2022-11-28)Complexes [(NHC)MCl] (M = coinage metal) have been evaluated as catalyst for the olefin aziridination reaction using PhI=NTs as nitrene source, with moderate to high activity being found depending of the metal and the ... -
Micellar Catalysis as a Tool for C-H Bond Functionalization To-ward C-C Bond Formation
(American Chemical Society, 2022-11-28)Micelles generated upon dissolving surfactants in water can be employed as nano-vessels for catalytic transformations, in the so-called micellar catalysis methodology. This review is focused onto the use of micellar ... -
Gold nanoparticle-catalysed functionalization of carbon-hydrogen bonds by carbene transfer reactions
(Royal Society of Chemistry, 2022-02-23)Gold nanoparticles stabilized by NHC ligands and supported onto reduced graphene oxide (rGO) catalyse the functionalization of cyclohexane and benzene C-H bonds upon insertion of carbene CHCO2Et (from N2=CHCO2Et) groups. ... -
Direct Benzene Hydroxylation with Dioxygen Induced by Copper Complexes: Uncovering the Active Species by DFT Calculations
(America Chemical Society, 2022-07-14)The direct oxidation of benzene into phenol using molecular oxygen at very mild temperatures can be promoted in the presence of the copper complex TpBr3Cu(NCMe) in the homogeneous phase in the presence of ascorbic acid as ... -
Selective Functionalization of Arene C(sp2 )−H Bonds by Gold Catalysis: The Role of Carbene Substituents
(American Chemical Society, 2022-05-25)The complete regioselective incorporation of carbene units to nonactivated arene rings has been achieved employing gold(I) catalysts bearing alkoxydiaminophosphine ligands, with readily available, nonelaborated ethyl ... -
Metal-Catalyzed Postpolymerization Strategies for Polar Group Incorporation into Polyolefins Containing C–C, C═C, and Aromatic Rings
(American Chemical Society, 2021-05-19)Polymeric materials bearing polar groups constitute a class of macromolecules with interest in a number of uses. Because the direct synthesis employing polymerization strategies from polar monomers is very often precluded ... -
Introducing the Catalytic Amination of Silanes via Nitrene Insertion
(American Chemical Society, 2022-06-01)The direct functionalization of Si−H bonds by the nitrene insertion methodology is described. A copper(I) complex bearing a trispyrazolylborate ligand catalyzes the transfer of a nitrene group from PhINTs to the Si−H bond ... -
Solubility of Methane in Water: Some Useful Results for Hydrate Nucleation
(American Chemical Society, 2022)In this paper, the solubility of methane in water along the 400 bar isobar is determined by computer simulations using the TIP4P/Ice force field for water and a simple LJ model for methane. In particular, the solubility ... -
Mechanistic Studies on the Synthesis of Pyrrolidines and Piperidines via Copper-Catalyzed Intramolecular C–H Amination
(American Chemical Society, 2022)We have recently developed a method for the synthesis of pyrrolidines and piperidines via intramolecular C–H amination of N-fluoride amides using [TpxCuL] complexes as precatalysts [Tpx = tris(pyrazolyl)borate ligand and ... -
Density functional theory for the prediction of interfacial properties of molecular fluids within the SAFT-g coarse-grained approach
(Royal Society of Chemistry, 2022)Recently, we have proposed the SAFT-VR Mie MF DFT approach [Algaba et al., Phys. Chem. Chem. Phys., 2019, 21, 11937–11948] to investigate systems that exhibit fluid–fluid interfaces. This formalism is based on the combination ... -
Arylisoquinoline-derived organoboron dyes with a triaryl skeleton show dual fluorescence
(Beilstein-Institut, 2019)Four new dyes that derive from borylated arylisoquinolines were prepared, containing a third aryl residue (naphthyl, 4-methoxynaphthyl, pyrenyl or anthryl) that is linked via an additional stereogenic axis. The triaryl ... -
Impact of Old Pb Mining and Metallurgical Production in Soils from the Linares Mining District (Spain)
(MDPI, 2022)Mineral processing and metallurgy production centers may leave a far-reaching fingerprint of soil contamination. This scenario is particularly relevant in the mining district of Linares (Southern Spain), where former ... -
Contribution of anthropogenic and natural sources in PM10 during North African dust events in Southern Europe
(Elsevier, 2021)The influence of North African (NAF) dust events on the air quality at the regional level (12 representative monitoring stations) in Southern Europe during a long time series (2007–2014) was studied. PM10 levels and ... -
