Aerobic Intramolecular Carbon-Hydrogen Bond Oxidation Promoted by Cu(I) Complexes
Álvarez, María; Molina, Francisco; Romero Fructos-Vázquez, Manuel
; Urbano Baena, Juan; Álvarez, Eleuterio; Sodupe, Mariona; Lledós, Agustí; Pérez Romero, Pedro José (Royal Society of Chemistry, 2020-09)
The oxidation of C–H bonds by copper centres in enzymes with molecular oxygen takes place in nature under ambient conditions. Herein we report a similar transformation in which under ambient pressure and temperature (1 ... -
Catalytic cyclopropanation of polybutadienes
Urbano Baena, Juan; Korthals, Brigitte; Díaz Requejo, María Mar; Pérez Romero, Pedro José; Mecking, Stefan (Wiley, 2010)
Catalytic cyclopropanation of commercial 1,2- or 1,4- cis -polybutadiene, respectively, with ethyl diazoacetate catalyzed by [Tp Br3 Cu(NCMe)] (Tp Br3 ¼ hydrotris(3,4,5-tribromo-1-pyrazo- lyl)borate) at room ... -
Copper(I)-Arene Complexes with a Sterically Hindered Tris(pyrazolyl)borate Ligand
Álvarez, María; Urbano Baena, Juan; Romero Fructos-Vázquez, Manuel; Álvarez, Eleuterio; Pérez Romero, Pedro José (Wiley-VCH Verlag, 2018)
A series of arene copper(I) complexes bearing the hydrotris(3-mesitylpyrazolyl)borate ligand (Tp(Ms)) of general formula Tp(Ms)Cu(arene) (arene = toluene, 1; nitrobenzene, 2; chlorobenzene, 3; and iodobenzene, 4) has been ... -
Copper-Induced Ammonia N-H Functionalization
Álvarez, María; Álvarez, Eleuterio; Romero Fructos-Vázquez, Manuel; Urbano Baena, Juan; Pérez Romero, Pedro José (Royal Society of Chemistry, 2016)
The activation of ammonia has been achieved with the aid of the TpMsCu core (TpMs = hydrotris(3-mesityl-pyrazolyl)borate). Complexes of the general composition TpMsCu(amine) (1–4) including the ammonia adduct TpMsCu(NH3) ... -
Enhanced wastewater bioremediation by a sulfur-based copolymer as scaffold for microalgae immobilization (AlgaPol)
León Vaz, Antonio; Cubero Cardoso, Juan; Trujillo Reyes, Ángeles; González Fermoso, Fernando; León Bañares, Rosa María; Funk, Christiane; Vigara Fernández, Javier; Urbano Baena, Juan (Elsevier, 2023)
In recent years, there has been an increasing concern related to the contamination of aqueous ecosystems by heavy metals, highlighting the need to improve the current techniques for remediation. This work intends to address ... -
Evidencing an inner-sphere mechanism for NHC-Au(I)- catalyzed carbene-transfer reactions from ethyl diazoacetate
Romero Fructos-Vázquez, Manuel; Urbano Baena, Juan; Díaz Requejo, María Mar; Pérez Romero, Pedro José (Beilstein-Institut, 2015)
Kinetic experiments based on the measurement of nitrogen evolution in the reaction of ethyl diazoacetate (N2CHCO2Et, EDA) and styrene or methanol catalyzed by the [IPrAu]+ core (IPr = 1,3-bis(diisopropylphenyl)imidazole ... -
Mechanism of Side Reactions in Alkane C-H Bond Functionalization by Diazo Compounds Catalyzed by Ag and Cu Homoscorpionate Complexes—A DFT Study
Braga, Ataualpa A. C.; Caballero Bevia, Ana; Urbano Baena, Juan; Díaz Requejo, María Mar; Pérez Romero, Pedro José; Maseras, Feliu (Wiley-VCH Verlag, 2011)
DFT computational methods were applied to the mechanistic study of the formation of fumarate and maleate derivatives in a solution containing alkane, TpBr3M [M=Cu, Ag; TpBr3=hydrotris(3,4,5-tribromopyrazolyl)borate] and ... -
Mesophilic Semi-Continuous Anaerobic Digestion of Strawberry Extrudate Pretreated with Steam Explosion
Cubero Cardoso, Juan; Muñoz Arjona, Andrés; Trujillo Reyes, Ángeles; Urbano Baena, Juan (MDPI, 2020-12)
The production of strawberry concentrate produces a side stream after extrusion that is commonly landfilled. This strawberry extrudate (SE), of lignocellulosic character, contains valuable bioactive compounds such as ... -
Promising Chalcogenide Hybrid Copolymers for Sustainable Applications as Bio-lubricants and Metal Adsorbents
Cubero Cardoso, Juan; Cuadri Vega, Antonio Abad; González Fermoso, Fernando; Martín Alfonso, José Enrique; Urbano Baena, Juan (American Chemical Society, 2022)
Inverse vulcanization has emerged as a reaction to achieve hybrid inorganic–organic polymeric materials, which allows us to use the high amount of sulfur produced during refining crude oil as a raw material. In this study, ... -
Structuring natural deep eutectic solvents with epoxidised ligninenriched residues: a green alternative to petroleum-based thickened formulations
Cortes Triviño, Esperanza; Cubero Cardoso, Juan; Tenorio Alfonso, Adrián; Fernández Recamales, María Ángeles; Valencia Barragán, Concepción; Urbano Baena, Juan; Franco Gómez, José María (Elsevier, 2022-05-23)
Natural deep eutectic solvents (NADESs) differing in the number of hydroxyl groups in the hydrogen bond donor (HBD) compound were investigated for usage as a matrix base in reactions involving a lignin-enriched fraction. ... -
Valorization of residual strawberry extrudate througt obtaining high added value compounds and methane production by anaerobic digestion
(Universidad de Huelva, 2021)Strawberry is used not only for direct consumption due to its excellent nutritional properties, but is also used for the manufacture of other products derived from the transformation of the fruit, such as jams, yogurts, ...
