Air-Stable, Dinuclear and Tetranuclear sigma,pi-Acetylide Gold(I) Complexes and Their Catalytic Implications

Grirrane, Abdessamad; García Gómez, Hermenegildo; Corma Canós, Avelino; Alvarez González, Eleuterio (John Wiley & Sons, 2013)

[EN] Two for one gold: Factors governing the formation of isolable digold(I) ó,ð-acetylide complexes are given (see scheme), indicating the general tendency of phosphine AuI precatalysts to form this type of complexes, ...
Catalysis at the Heart of Success!

Bornscheuer, Uwe T.; Hashmi, A. Stephen K.; García Gómez, Hermenegildo; Rowan, Michael A. (John Wiley & Sons, 2017)
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 ...
Double A(3)-Coupling of Primary Amines Catalysed by Gold Complexes

Grirrane, Abdessamad; Alvarez-González, Eleuterio; García Gómez, Hermenegildo; Corma Canós, Avelino (John Wiley & Sons, 2018)

[EN] A novel family of dipropargylamines has been synthesized in one pot through a double catalytic A3-coupling of five component. Several reactions of LAu-amine complexes with organic reagents were studied and followed ...
Efficient chirality switching in the addition of diethylzinc to aldehydes in the presence of simple chiral alpha-amino amides

Burguete, M.I.; Collado, M.; Escorihuela Fuentes, Jorge; Luis Lafuente, Santiago (Wiley, 2007-09)
Isolation and X-ray characterization of palladium N complexes in the guanylation ofaromatic amines. Mechanistic implications

Grirrane, Abdessamad; García Gómez, Hermenegildo; Álvarez, Eleuterio (Beilstein-Institut, 2013-07-22)

In the context of palladium-catalyzed guanylation of anilines herein, we have been able to characterize and isolate bis(anilino) and bis(guanidino)Pd(II) complexes using reaction conditions under which stoichiometric ...
Polymer- and Ionic Liquid-Containing Palladium: Recoverable Soluble Cross-Coupling Catalysts

Navalón Oltra, Sergio; Alvaro Rodríguez, Maria Mercedes; García Gómez, Hermenegildo (Wiley-VCH Verlag, 2013-12)

[EN] Phosphine, palladacycle, and N-heterocyclic carbene palladium complexes are highly active homogeneous catalysts that can promote a wide range of CC and CN cross-coupling reactions. An evolution from homogeneous catalysis ...
Preparation of Tremorine and Gemini Surfactant Precursors with Cationic Ethynyl-Bridged Digold Catalysts

Grirrane, Abdessamad; Alvarez-González, Eleuterio; García Gómez, Hermenegildo; Corma Canós, Avelino (John Wiley & Sons, 2017)

[EN] Tremorine and precursors of gemini surfactants were synthesised in a one-pot, three-step, double-catalytic A3 coupling reaction and characterised by structural and spectroscopic methods. The cationic [Au-I(L1)]SbF6 ...
Synthesis, Structure, Reactivity and Catalytic Implications of a Cationic, Acetylide-Bridged Trigold-JohnPhos Species
