Catalyst Enhancement and Recyclability by Immobilization of Metal Complexes onto Graphene Surface by Noncovalent Interactions
ACS Publications (2014-05-14)The immobilization of a homogeneous catalyst onto a solid surface is one of the major challenges in catalysis, because it may facilitate the separation of the catalyst and the reaction products and may also give rise to ... -
Double CH bond activation of C(sp3)H2 groups for the preparation of complexes with back-to-back bisimidazolinylidenes
Wiley (2011-06-29)Two-headed carbenes: N-heterocyclic carbene complexes of rhodium and iridium were obtained by the double CH activation of CH2 groups in N heterocycles (see structure: C gray, N blue, Cl green, Ir pink). The reaction ... -
Experimental and Theoretical Approaches to the Influence of the Addition of Pyrene to a Series of Pd and Ni NHC-Based Complexes: Catalytic Consequences
Wiley (2014-11-20)A series of Ni and Pd complexes with three different N-heterocyclic carbene (NHC)-based ligands (imidazolylidene, benzimidazolylidene and pyrene–imidazolylidene) has been prepared and fully characterized. The influence of ... -
Palladium N-Heterocyclic Carbene Catalysts for the Ultrasound-Promoted Suzuki-Miyaura Reaction in Glycerol
Wiley (2013-04-15)Novel palladium N-heterocyclic-carbene (NHC)-based complexes with 3,4,5-trimethoxybenzyl, alkyl and sulfonate N-substituents were obtained and fully characterized. The new complexes were used as pre-catalysts in the ... -
Perceptible Influence of Pd and Pt Heterocyclic Carbene–Pyridyl Complexes in Catalytic Diboration of Cyclic Alkenes
Wiley-VCH (2010)Bis(catecholato)diboron was added to cyclic alkenes with internal strain to selectively form bis(boryl)cycloalkanes quantitatively in the presence of [Pd(NHC)pyCl2], [Pd(NHC)pyI2], and [Pt(NHC)pyI2] (NHC=N-heterocyclic ... -
Recent developments in the applications of palladium complexes bearing N-heterocyclic carbene ligands
Bentham Science Publishers (2011-01-09)N-heterocyclic carbene (NHC) ligands have become ubiquitous ligands in the preparation of metal complexes with new catalytic applications. Mainly due to their applications in C-C bond formation reactions, a plethora of ... -
Ruthenium molecular complexes immobilized on graphene as active catalysts for the synthesis of carboxylic acids from alcohol dehydrogenation
Royal Society of Chemistry (2016-09)Ruthenium complexes containing N-heterocyclic carbene ligands functionalized with different polyaromatic groups (pentafluorophenyl, anthracene, and pyrene) are immobilized onto the surface of reduced graphene oxide. The ... -
Unveiling the Importance of π-Stacking in Borrowing-Hydrogen Processes Catalysed by Iridium Complexes with Pyrene Tags
Wiley (2015-09-10)This work describes the preparation of a series of pyrene-tagged N-heterocyclic carbene complexes of iridium, and their use in two benchmark borrowing hydrogen reactions: the reduction of ketones by transfer hydrogenation ... -
Water-soluble IrIII n-heterocyclic carbene based catalysts for the reduction of CO2 to formate by transfer hydrogenation and the deuteration of aryl amines in water
WILEY-VCH Verlag (2011-03-01)Two new water-soluble [IrI2(AcO)(bis-NHC)] complexes (NHC=N-heterocyclic carbene) incorporating a sulfonate functionality have been synthesized. The two complexes have been tested in the reduction of CO2 with H2 and iPrOH, ...
