[EN] The assumption that oxidative addition is the key step during the cross-coupling reaction of aryl halides has led to the development of a plethora of increasingly complex metal catalysts, thereby obviating in many ...
Cationic Gold Catalyzes Omega-Bromination of Terminal Alkynes and Subsequent Hydroaddition Reactions

Leyva Perez, Antonio; Rubio Marqués, Paula; AL-Dejab, Salem S.; Al-Resayes, Saud I.; Corma Canós, Avelino (American Chemical Society, 2011)

[EN] Orthogonal sigma,pi-bisfunctionalization of terminal alkynes can be achieved with a cationic gold complex in catalytic amounts. First, the terminal C-H bond is transformed to the corresponding bromoalkyne which is ...
Control electrónico de metales preciosos soportados para catalizar reacciones de formación carbono-nitrógeno e hidrogenación de anillos aromáticos

Rubio Marqués, Paula (Universitat Politècnica de València, 2017-02-17)

In this thesis, different solids-containing precious metals has been prepared with controlled size and electronics, and used as catalysts for hydrogenation and hydroadition reactions, among others, obtaining prod-ucts of ...
Diseño de catalizadores metálicos soportados para procesos "one-pot" de hidrogenación-acoplamiento de aminas-hidrogenación a partir de compuestos nitroaromáticos

Rubio Marqués, Paula (Universitat Politècnica de València, 2012-05-11)

El acoplamiento entre aminas para obtener aminas secundarias es, hoy en día, una reacción poco desarrollada. En este trabajo, conseguimos hidrogenar el nitrobenceno para dar la correspondiente amina secundaria usando ...
Intimate ruthenium-platinum nanoalloys supported on carbon catalyze the hydrogenation and one-pot hydrogenation-coupling reaction of oxidized amino derivatives

Rivero-Crespo, Miguel A.; Rubio Marqués, Paula; Hernández-Garrido, Juan Carlos; Mon-Conejero, Marta; Oliver-Meseguer, Judit; Leyva Perez, Antonio (The Royal Society of Chemistry, 2023-04-24)

[EN] The use of bimetallic nanoparticles as catalysts in complex organic synthesis is rare, despite the widespread use of these materials in thermal C-1 chemistry and electrocatalysis. Here we show that intimate RuPt ...
One pot synthesis of cyclohexanone oxime from nitrobenzene using a bifunctional catalyst

Rubio Marqués, Paula; Hernández Garrido, Juan Carlos; Leyva Perez, Antonio; Corma Canós, Avelino (Royal Society of Chemistry, 2014)

Cyclohexanone oxime is formed from nitrobenzene with 97% yield in a one-pot reaction catalysed by palladium and gold nanoparticles on carbon. The reaction is carried out under hydrogen at 60 8C and the overall transformation ...
Reactivity of Electron-Deficient Alkynes on Gold Nanoparticles

Leyva Perez, Antonio; Oliver Meseguer, Judit; Cabrero Antonino, Jose Ramón; Rubio Marqués, Paula; Serna, Pedro; Al-Resayes, Saud I.; Corma Canós, Avelino (American Chemical Society, 2013-07)

[EN] Propiolates cyclotrimerize in the presence of catalytic amounts of gold nanoparticles to give aryl benzoates in high yields and with turnover frequencies of thousands per hour. Types of alkynes other than propiolates ...
Synthesis of Organic-Inorganic Hybrid Solids with Copper Complex Framework and Their Catalytic Activity for the S-Arylation and the Azide-Alkyne Cycloaddition Reactions

Cabrero Antonino, Jose Ramón; García Fernández, María Teresa; Rubio Marqués, Paula; Vidal Moya, José Alejandro; Leyva Perez, Antonio; Al-Deyab, Salem S.; Al-Resayes, Saud I.; Díaz Morales, Urbano Manuel; Corma Canós, Avelino (American Chemical Society, 2011)
