Catalytic Activity of Cationic and Neutral Silver(I)-XPhos Complexes with Nitrogen Ligands or Tolylsulfonate for Mannich and Aza-Diels-Alder Coupling Reactions

Grirrane, Abdessamad; Alvarez-González, Eleuterio; García Gómez, Hermenegildo; Corma Canós, Avelino (John Wiley & Sons, 2016)

[EN] Cationic and neutral silver(I)-L complexes (L = Buchwald-type biaryl phosphanes) with nitrogen co-ligands or organosulfonate counter ions have been synthesised and characterised through their structural and spectroscopic ...
Cationic Copper(I) complexes as highly efficient catalysts for single and double A(3)-coupling mannich reactions of terminal alkynes: Mechanistic insights and comparative studies with analogous Gold (I) complexes

Grirrane, Abdessamad; Alvarez, Eleuterio; García Gómez, Hermenegildo; Corma Canós, Avelino (Wiley-VCH Verlag, 2014-10-27)

[EN] Cationic Cu L complexes (L=Buchwald-type phosphane) with N co-ligands have been characterised by structural and spectroscopic properties. These copper(I) complexes are extremely active catalysts, far more active than ...
Cobalt Catalysts for Alkene Hydrosilylation under Aerobic Conditions without Dry Solvents or Additives

Gutiérrez-Tarriño, Silvia; Concepción Heydorn, Patricia; Oña-Burgos, Pascual (John Wiley & Sons, 2018-12-06)

[EN] Alkene hydrosilylation is typically performed with Pt catalysts, but inexpensive base-metal catalysts would be preferred. Here, we report a simple method for the use of air-stable cobalt catalysts for anti-Markovnikov ...
Efficient Synthesis of 5-Chalcogenyl-1,3-oxazin-2-ones by Chalcogen-Mediated Yne Carbamate Cyclisation: An Experimental and Theoretical Study

Monleón, Alicia; Blay, Gonzalo; Domingo, Luis R.; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley-VCH Verlag, 2015-02)

A very efficient synthesis of 5-chalcogenyl-1,3-oxazin-2-ones has been accomplished by the chalcogen-mediated yne-carbamate cyclisation of chiral, non-racemic N-Cbz-protected propargylic amines using PhXY (X = Se, S, Te; ...
Exploring the Mechanisms and Kinetic Modeling of Phenol Amination Using Pd and Rh-Based Catalysts

Ortega, Maray; Garrido, Benjamin; Gómez-Acosta, Daviel; Fernandez-Andrade, Alex Ariel; Domine, Marcelo Eduardo; Jiménez, Romel; Arteaga-Pérez, Luis E (John Wiley & Sons, 2024-09-30)

[EN] Producing biomass-derived chemicals to substitute their petrochemical counterparts has long been an aspiration of the green chemistry research community. However, synthesizing secondary amines from biomass precursors ...
Ketone Formation from Carboxylic Acids by Ketonic Decarboxylation: The Exceptional Case of the Tertiary Carboxylic Acids

Oliver-Tomás, Borja; Renz, Michael; Corma Canós, Avelino (John Wiley & Sons, 2017-09-18)

[EN] For the reaction mechanism of the ketonic decarboxylation of two carboxylic acids, a -keto acid is favored as key intermediate in many experimental and theoretical studies. Hydrogen atoms in the -position are an ...
Perylene-Grafted Silicas: Mechanistic Study and Applications in Heterogeneous Photoredox Catalysis

Carrillo, Adela I.; Elhage, Ayda; Marín García, Mª Luisa; Lanterna, Anabel E. (John Wiley & Sons, 2019-11-22)

[EN] A mechanistic study is herein presented for the use of heterogeneous photocatalysts based on perylene moieties. First, the successful immobilization of perylene diimides (PDI) on silica matrices is demonstrated, ...
Synthesis of Densely Functionalised 5-Halogen-1,3-oxazin-2-ones byHalogen-Mediated Regioselective Cyclisation of N-Cbz-ProtectedPropargylic Amines: A Combined Experimental and Theoretical Study

Monleon, Alicia; Blay, Gonzalo; Domingo, Luis R.; Muñoz Roca, María del Carmen; Pedro, José R. (Wiley-VCH Verlag, 2013-10-25)

A very efficient synthesis of 5-halogen-1,3-oxazin-2-ones has been accomplished by the halocyclisation reaction of chiral nonracemic N-carbobenzyloxy (N-Cbz)-protected propargylic amines by using I-2, Br-2 and Cl-2 as ...
Synthesis, Structure, Reactivity and Catalytic Implications of a Cationic, Acetylide-Bridged Trigold-JohnPhos Species

Grirrane, Abdessamad; Álvarez, Eleuterio; García Gómez, Hermenegildo; Corma Canós, Avelino (John Wiley & Sons, 2020-07-17)

[EN] The cationic complex [(JohnPhos-Au)(3)(acetylide)][SbF6] (JohnPhos=(2-biphenyl)di-tert-butylphosphine, L1) has been characterised structurally and features an acetylide-trigold(I)-JohnPhos system; the trinuclear-acetylide ...
Transformation of Cellulose into Biodegradable Alkyl Glycosides by Following Two Different Chemical Routes

Villandier, Nicolas; Corma Canós, Avelino (Wiley-VCH Verlag, 2011-04-18)

The transformation of cellulose into long-chain alkyl glycoside surfactants has been carried out following two different routes: (1) Direct transformation of cellulose to butyl-, hexyl-, octyl-, decyl- and dodecyl-a,ß-glycosides ...
