Electrochemical reduction of HMF to synthesize added value compounds using CuAg electrodes
Carvajal, David; Bolos-Sánchez, Victoria; Solera Rojas, Jose; Mejuto, Carmen; Fabregat-Santiago, Francisco; Mas, Elena Elsevier (2023-12-16)In biorefining, Green electrochemistry offers an intelligent approach to produce valuable chemicals that are not derived from fossil fuels. In this study, we demonstrate the electrochemical reduction of 5-hydroxymethylfurfural ... -
First homoleptic MIC and heteroleptic NHC-MIC coordination cages from 1,3,5-triphenylbenzene-bridged tris-MIC and tris-NHC ligands
Mejuto, Carmen; Guisado-Barrios, Gregorio; Gusev, Dmitry; Peris, Eduardo Royal Society of Chemistry (2015-07-24)The preparation of a triphenylbenzene-bridged tris-(1,2,3-triazolium) salt allowed us to obtain the first homoleptic tris-MIC cylinder-like cages of Ag and Au. The silver MIC-based cage reacts with the trisNHC-Ag analogue ... -
Introducing Catalysis to Undergraduate Chemistry Students: Testing a Ru–NHC Complex in the Selective Dehydrogenative Coupling of Hydrosilanes and Alcohols
Mollar Cuni, Andrés; Mejuto, Carmen; Ventura Espinosa, David; Borja, María Pilar; Mata Martínez, Jose A American Chemical Society (2021-07-14)This work describes a complete laboratory experiment that involves the synthesis of a ruthenium complex [Ru(p-cym)(NHC)Cl2] (NHC = N-heterocyclic carbene) and its use as a catalyst for the coupling of hydrosilanes and ... -
Novel rhodium and iridium complexes coordinated to C3‑symmetric tris-NHC ligands based on a 1,3,5-triphenylbenzene core. Electronic and catalytic properties
Mejuto, Carmen; Guisado-Barrios, Gregorio; Peris, Eduardo American Chemical Society (2014)A series of novel tris-azolium salt precursors based on 1,3,5- triphenylbenzene have been prepared. These salts exhibit fluorescence emission in the 320−420 nm region. The coordination of these salts to [MCl(COD)]2 (M ... -
Rhodium, iridium and nickel complexes with a 1,3,5-triphenylbenzene tris-MIC ligand. Study of the electronic properties and catalytic activities
Mejuto, Carmen; Royo, Beatriz; Guisado-Barrios, Gregorio; Peris, Eduardo Beilstein-Institut (2015-12-14)The coordination versatility of a 1,3,5-triphenylbenzene-tris-mesoionic carbene ligand is illustrated by the preparation of complexes with three different metals: rhodium, iridium and nickel. The rhodium and iridium complexes ... -
Ruthenium complexes with an N-heterocyclic carbene NNC-pincer ligand: preparation and catalytic properties
Mejuto, Carmen; García-Eleno, Marco A.; Guisado-Barrios, Gregorio; Spasyuk, Denis; Gusev, Dmitry; Peris, Eduardo Royal Society of Chemistry (2015-06)1-Methyl-3-(2-((pyridin-2-ylmethylene)amino)ethyl)-1H-imidazol-3-ium bromide was prepared and used as an N-heterocyclic carbene NNC-pincer ligand precursor. Depending on the coordination strategy, a monometallic ... -
Self-Assembly of Di-N-Heterocyclic Carbene-Gold-Adorned Corannulenes on C60
Mejuto, Carmen; Escobar, Luis; Guisado-Barrios, Gregorio; Ballester, Pablo; Goussev, Dmitri; Peris, Eduardo Wiley (2017-08-04)The deprotonation of a corannulene-based bisazolium salt allowed the preparation of a corannulene-based NHC di-AuI complex. The prepared di-AuI-complex was tested in the recognition of fullerene-C60, demonstrating good ... -
Synthesis of nanometer-sized cylinder-like structures from a 1,3,5- triphenylbenzene-bridged tris-NHC ligand and AgI , AuI , and CuI
Sinha, Narayan; Roelfes, Florian; Hepp, Alexander; Mejuto, Carmen; Peris, Eduardo; Hahn, Franz Ekkehardt American Chemical Society (2014)The metal-controlled self-assembly of nanometer-sized trinuclear cylinder-like assemblies is described. The 1,3,5-triphenylbenzene-derived trisimidazolium salt [1](PF6)3 reacts with 1.5 equiv of Ag2O to yield the ... -
Visible light harvesting alkyne hydrosilylation mediated by pincer platinum complexe
Ibañez-Ibañez, Laura; Lázaro, Ariadna; Mejuto, Carmen; Crespo, Margarita; Vicent Barrera, Cristian; Rodríguez, Laura; Mata Martínez, Jose A Elsevier (2023-12)In this manuscript we assess the catalytic properties of pincer platinum complexes in alkyne hydrosilylation either under photo or thermal conditions. The visible light-induced hydrosilylation proved to be more efficient. ... -
