A Ligand-Free Pt3 Cluster Catalyzes the Markovnikov Hydrosilylation of Alkynes with up to 106 Turnover Frequencies

Rivero-Crespo, Miguel Ángel; Leyva Perez, Antonio; Corma Canós, Avelino (John Wiley & Sons, 2017)

[EN] The Pt-catalyzed hydrosilylation of alkynes is the procedure of choice to obtain vinylsilanes, and is claimed to be the most relevant application of Pt in organic synthesis. More than half a century after its discovery, ...
Catalytic Enantioselective Conjugate Alkynylation of α,β-Unsaturated 1,1,1-Trifluoromethyl Ketones with Terminal Alkynes

Sanz Marco, Amparo; Blay, Gonzalo; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley, 2016-07-11)

The first catalytic enantioselective conjugate alkynylation of α,β-unsaturated 1,1,1-trifluoromethyl ketones has been carried out. Terminal alkynes and 1,3-diynes were treated with trifluoromethyl ketones in the presence ...
Clusters and single atoms of Pd and Pt: Synthesis and applications in catalysis and as antitumoral agents

Greco, Rossella (Universitat Politècnica de València, 2021-09-02)

[ES] En esta tesis se han estudiado la síntesis y aplicación de clústeres y átomos metálicos aislados de Pd y Pt. Clústeres y átomos aislados han sido sintetizados siguiendo nuevas metodologías en disolución, sin utilizar ...
Gold nanoclusters supported on different materials as catalysts for the selective alkyne semihydrogenation

López-Hernández, I.; Truttmann, V.; Barrabés, N.; Rupprechter, G.; Rey Garcia, Fernando; Mengual Cuquerella, Jesús; Palomares Gimeno, Antonio Eduardo (Elsevier, 2022-07-01)

[EN] Catalysts based on gold nanoclusters supported by different materials have been used for the selective semi hydrogenation of phenylacetylene to styrene. The most active species were formed by catalyst thermal activation ...
Materiales basados en especies de Pd soportadas sobre matrices sólidas como catalizadores eficientes para reacciones de interés en química fina

Arango Daza, Juan Camilo (Universitat Politècnica de València, 2024-01-03)

[ES] La presente tesis doctoral se basa en la síntesis, caracterización y uso de catalizadores basados en especies de Pd soportadas sobre matrices sólidas en reacciones de interés en química fina. En general, se ha pretendido ...
MOF-Triggered Synthesis of Subnanometer Ag02 Clusters and Fe3+ Single Atoms: Heterogenization Led to Efficient and Synergetic One- Pot Catalytic Reactions

Tiburcio, Estefanía; Zheng, Yongkun; Bilanin-Artigado, Cristina; Hernández-Garrido, Juan Carlos; Vidal Moya, José Alejandro; Oliver-Meseguer, Judit; Martín-García, Nuria; Mon-Conejero, Marta; Ferrando-Soria, Jesus; Armentano, Donatella; Leyva Perez, Antonio; Pardo, Emilio (American Chemical Society, 2023-05-10)

[EN] The combination of well-defined Fe3+ isolated single-metal atoms and Ag2 subnanometer metal clusters within the channels of a metal¿organic framework (MOF) is reported and characterized by single-crystal X-ray diffraction ...
One-Pot Synthesis of Terminal Alkynes from Alkenes

Bilanin-Artigado, Cristina; Singh, Amravati Shivaji; Martínez-Belenguer, Lluis; Leyva Perez, Antonio (American Chemical Society, 2024-08-05)

[EN] The direct synthesis of terminal alkynes from widely available terminal alkenes is an unmet challenge in organic synthesis. Here, we show that alkyl and aromatic terminal alkenes can be converted to the corresponding ...
Regioselective Hydration of Alkynes by Iron(III) Lewis/Brønsted Catalysis

Cabrero Antonino, Jose Ramón; Leyva Perez, Antonio; Corma Canós, Avelino (Wiley-VCH Verlag, 2012-08-27)

The triflimide iron(III) salt [Fe(NTf2)3] promotes the direct hydration of terminal and internal alkynes with very good Markovnikov regioselectivities and high yields. The enhanced carbophilic Lewis acidity of the FeIII ...
Self-Assembly of Catalytically Active Supramolecular Coordination Compounds within Metal Organic Frameworks

Adam-Ortiz, Rosa; Mon, M.; Greco, Rossella; Kalinke, Lucas H.G.; Vidal Moya, José Alejandro; Fernandez, Antonio; Winpenny, Richard E.P.; Doménech-Carbó, Antonio; Leyva Perez, Antonio; Armetano, Donatella; Pardo, Emilio; Ferrando-Soria, Jesús (American Chemical Society, 2019-07-03)

[EN] Supramolecular coordination compounds (SCCs) represent the power of coordination chemistry methodologies to self-assemble discrete architectures with targeted properties. SCCs are generally synthesized in solution, ...
