Bifunctional acid-base ionic liquid for the one-pot synthesis of fine chemicals: thioethers, 2H-chromenes and 2H-quinoline derivatives

Climent Olmedo, María José; Iborra Chornet, Sara; Sabater Picot, Mª José; Vidal Castro, Juan Diego (Elsevier, 2014-07-05)

A bifunctional organocatalyst with ionic liquid properties and with an optimized distance between the acid and basic sites efficiently activates electron deficient olefins for 1,4 conjugated addition, which can be incorporated ...
Chemicals from Biomass: Chemoselective reductive amination of ethyl levulinate with amines

Vidal, Juan D; Climent Olmedo, María José; Concepción Heydorn, Patricia; Corma Canós, Avelino; Iborra Chornet, Sara; Sabater Picot, Mª José (American Chemical Society, 2015-10)

N-substituted-5-methyl-2-piyrrolidones have been obtained by reductive amination of ethyl levulinate with amines in the presence of H-2 as reducing agent under solvent-free conditions. The process involves as a first step ...
Chemicals from Biomass: Selective Synthesis of N-Substituted Furfuryl Amines by the One-Pot Direct Reductive Amination of Furanic Aldehydes

Garcia-Ortiz, Andrea; Vidal, Juan D; Climent Olmedo, María José; Concepción Heydorn, Patricia; Corma Canós, Avelino; Iborra Chornet, Sara (American Chemical Society, 2019-03-18)

[EN] N-substituted furfuryl amines are an important class of compounds due to their pharmaceutical activities that can be produced by reductive amination of furfuraldehydes derived from biomass. With supported Pd nanoparticles ...
Molecular Oxygen Lignin Depolymerization: An Insight into the Stability of Phenolic Monomers

Mathieu, Yannick; Vidal, Juan D; Arribas Martínez, Lourdes; Abad Fernández, Nerea; Iborra Chornet, Sara; Corma Canós, Avelino (John Wiley & Sons, 2020-09-07)

[EN] During oxidative depolymn. of lignin in aq. alk. medium using mol. oxygen as oxidant, the highly functionalized primary phenolic monomers are not stable products, owing to various not fully identified secondary ...
One-Pot Selective Catalytic Synthesis of Pyrrolidone Derivatives from Ethyl Levulinate and Nitro Compounds

Vidal, Juan D; Climent Olmedo, María José; Corma Canós, Avelino; Concepción Heydorn, Patricia; Iborra Chornet, Sara (John Wiley & Sons, 2017)

[EN] N-substituted 5-methyl-2-pyrrolidones were prepared in a one-pot process starting from ethyl levulinate and nitro compounds in the presence of a nanosized Pt-based catalyst. Pt supported on TiO2 nanotubes (Pt/TiO2-NT) ...
Organocatalizadores bifuncionales basados en líquidos iónicos para síntesis de heterocíclos en reacciones compatibles con la química verde

Vidal Castro, Juan Diego (Universitat Politècnica de València, 2013-06-24)

[ES] Sintesis de catalizadores con propiedades de líquido iónico y con bifuncionalidad acido-base. Siendo muy activos y selectivos para llevar a cabo la condensación de Knoevenagel, así como la adición de Michael, empleadolos ...
Synthesis of a hybrid Pd-0/Pd-carbide/carbon catalyst material with high for reactions

Garcia-Ortiz, Andrea; Vidal, Juan D.; Iborra Chornet, Sara; Climent Olmedo, María José; Cored-Bandrés, Jorge; Ruano-Sánchez, Daniel; Pérez-Dieste, Virginia; Concepción Heydorn, Patricia; Corma Canós, Avelino (Elsevier, 2020-09)

[EN] We present a highly selective and active Pd carbon catalyst prepared by an easy hydrothermal synthesis method. This synthetic procedure allows the stabilization under mild conditions of interstitial carbon atoms on ...
VALORACIÓN DE MOLÉCULAS PLATAFORMA DERIVADAS DE BIOMASA MEDIANTE AMINACIÓN REDUCTIVA UTILIZANDO NANOPARTÍCULAS METÁLICAS COMO CATALIZADORES HETEROGÉNEOS

Vidal Castro, Juan Diego (Universitat Politècnica de València, 2017-11-06)

In this Doctoral Thesis we present the valorization of raw materials derived from biomass, specifically ethyl levulinate and 5-hydroxymethylfurfural, by reductive amination with primary amines, using heterogeneous catalysts ...
