CATALIZADORES DE ORO SOPORTADOS PARA LA MONOALQUILACIÓN DE AMINAS CON ALCOHOLES A TRAVES DE UN PROCESO ONE-POT

Navas Escrig, Javier (Universitat Politècnica de València, 2011-11-28)

En el presente proyecto se ha tratado de estudiar la aplicabilidad de catalizadores heterogéneos basados en el oro como especie activa en la monolaquilación de aminas mediante el uso de alcoholes a través de un mecanismo ...
Coupling two multistep catalytic cycles for the one-pot synthesis of propargylamines from alcohols and primary amines on nanoparticulated gold catalyst

Corma Canós, Avelino; Navas Escrig, Javier; Sabater Picot, Mª José (Wiley-VCH Verlag, 2012)

[EN] A one-pot reaction was performed with a nanoparticulated gold catalyst. A secondary amine is formed through N-monoalkylation of a primary amine with an alcohol by a borrowing hydrogen methodology in a three-step ...
Exceptional oxidation activity with size-controlled supported gold clusters of low atomicity

Corma Canós, Avelino; Concepción Heydorn, Patricia; Boronat Zaragoza, Mercedes; Sabater Picot, Mª José; Navas Escrig, Javier; Yacaman, Miguel José; Larios, Eduardo; Posadas, Álvaro; López Quintela, M. Arturo; Buceta, David; Mendoza, Ernest; Guilera, Gemma; Mayoral, Álvaro (Nature Publishing Group, 2013-09)

[EN] The catalytic activity of gold depends on particle size, with the reactivity increasing as the particle diameter decreases. However, investigations into behaviour in the subnanometre regime (where gold exists as small ...
NANOPARTÍCULAS Y CLÚSTERES METÁLICOS SOPORTADOS PARA LA FORMACIÓN DE ENLACES C-O, C-N, C-S Y S-S

Navas Escrig, Javier (Universitat Politècnica de València, 2016-05-16)

[EN] During the work done in this thesis, new catalysts based on metallic nanoparticles and clusters supported on materials with different properties have been designed and developed trying to improve their stability and ...
One-Pot Palladium-Catalyzed Borrowing Hydrogen Synthesis of Thioethers

Corma Canós, Avelino; Navas Escrig, Javier; Ródenas Torralba, Tania; Sabater Picot, Mª José (John Wiley & Sons, 2013)

[EN] Palladium on magnesium oxide is able to allow a one-pot reaction to synthesize thioethers from thiols and aldehydes formed in situ from the respective alcohol by means of a borrowing hydrogen method. The reaction is ...
Synthesis of gamma-lactones from easily and accessible reactants catalyzed by Cu-MnOx catalysts

Sabate-Fornons, Ferran; Navas Escrig, Javier; Sabater Picot, Mª José; Corma Canós, Avelino (Elsevier, 2018)

[EN] The mechanism of the oxidative [3+2] cycloaddition of alkenes with anhydrides using oxygen as an oxidant to synthesize gamma-lactones has been studied using a heterogeneous dual copper-manganese-based catalyst. The ...
