Metal-Catalyzed Postpolymerization Strategies for Polar Group Incorporation into Polyolefins Containing C–C, C═C, and Aromatic Rings
Menendez Rodriguez, Gabril; Díaz Requejo, María Mar; Pérez Romero, Pedro José (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
Rodríguez, Anabel. M; Pérez Ruíz, Jorge; Molina, Francisco; Poveda, Ana; Pérez Soto, Raúl; Maseras, Feliu; Díaz Requejo, María Mar; Pérez Romero, Pedro José (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
Grabowska, Joanna; Blázquez, Samuel; Sanz, Eduardo; Zerón, Iván M.; Algaba Fernández, Jesús; Míguez, José Manuel; Jiménez Blas, Felipe; Vega, Carlos (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
Muñoz Molina, José María; Bafaluy, Daniel; Funes Ardoiz, Ignacio; Aguirre, Adiran J. de; Maseras, Feliu; Rodríguez Belderraín, Tomás; Pérez Romero, Pedro José; Muñiz, Kilian (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
Algaba Fernández, Jesús; Mendiboure, Bruno; Gómez Álvarez, Paula; Jiménez Blas, Felipe (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 ... -
