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 ...
Electrochemical monitoring of the oxidative coupling of alkynes catalyzed by triphenylphosphine gold complexes

Domenech Carbo, Antonio; Leyva Perez, Antonio; Al-Resayes, Saud I.; Corma Canós, Avelino (Elsevier, 2012-06)

Electrochemical monitoring of the oxidative coupling of alkynes in the homogeneous phase through catalytic cycles involving triphenylphosphine gold complexes and selectfluor as oxidant reveals that at least two gold species ...
Formation and stability of 3-5 atom gold clusters from gold complexes during the catalytic reaction: dependence on ligands and counteranions

Oliver Meseguer, Judit; Leyva Perez, Antonio; Al-Resayes, Saud I.; Corma Canós, Avelino (Royal Society of Chemistry, 2013-09-14)

Gold complexes and salts decompose to catalytically active 3¿5 atom gold clusters during the one-pot acylation¿hydration of propargyl alcohols. Kinetic and spectroscopic studies show that released ligands and counteranions ...
Gold Redox Catalytic Cycles for the Oxidative Coupling of Alkynes

Leyva Perez, Antonio; Doménech, Antonio; Al-Resayes, Saud I.; Corma Canós, Avelino (American Chemical Society, 2011-12)

[EN] Au(I)/Au(III) catalytic cycles are catalytically competent to perform the oxidative coupling of alkynes in the homogeneous phase at room temperature and without any protecting atmosphere. Selectfluor as oxidant, wet ...
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)

[EN] Two di¿erent diamines, namely, Tr¿oger base and dimethylethylene diamine (DMEDA) functionalized with disilane groups, have been condensed with silica precursors to form mesoporous hybrid organic-inorganic materials. ...
Synthesis of the ortho/meta/para Isomers of relevant pharmaceutical compounds by coupling a sonogashira reaction with a regioselective hydration

Leyva Perez, Antonio; Cabrero Antonino, Jose Ramón; Rubio Marqués, Paula; Al-Resayes, Saud I.; Corma Canós, Avelino (American Chemical Society, 2014-03)

Aryl ketones substituted in ortho, meta, and para position are prepared by a palladium-catalyzed Sonogashira reaction followed by a regioselective hydration of the soformed alkyne with triflimidic acid or a gold catalyst, ...
