Gold nanoparticle-catalysed functionalization of carbon-hydrogen bonds by carbene transfer reactions
Martínez Laguna, Jonathan; Mollar Cuni, Andrés; Ventura Espinosa, David; Martín Solans, Santiago; Caballero Bevia, Ana; Mata Martínez, Jose A; Perez, Pedro J. The Royal Society of Chemistry (2022-02-23)Gold nanoparticles stabilized by NHC ligands and supported onto reduced graphene oxide (rGO) catalyse the functionalization of cyclohexane and benzene C–H bonds upon insertion of carbene CHCO2Et (from N2[double bond, length ... -
High Production of Hydrogen on Demand from Silanes Catalyzed by Iridium Complexes as a Versatile Hydrogen Storage System
Ventura Espinosa, David; Sabater, Sara; Carretero Cerdán, Alba; Baya, Miguel; Mata Martínez, Jose A American Chemical Society (2018)The catalytic dehydrogenative coupling of silanes and alcohols represents a convenient process to produce hydrogen on demand. The catalyst, an iridium complex of the formula [IrCp*(Cl)(2)(NHC)] containing an N-heterocyclic ... -
Improving Catalyst Activity in Hydrocarbon Functionalization by Remote Pyrene-Graphene Stacking
Ballestin, Pilar; Ventura Espinosa, David; Santiago Martín; Martín Solans, Santiago; Caballero, Ana; Mata Martínez, Jose A; Pérez, Pedro J. Wiley (2019)A copper complex bearing an N-heterocyclic carbene ligand with a pyrene "tail" attached to the backbone has been prepared and supported on reduced graphene oxide (rGO). The free and supported copper materials have been ... -
