A nano-sized Janus di-N-heterocyclic carbene ligand based on a quinoxalinophenanthrophenazine core, and its coordina- tion to iridium
American Chemical Society (2015-04-21)A Janus-type bis-N-heterocyclic carbene ligand based on a quinoxalinophenanthrophenazine core has been obtained and coordinated to iridium. The electronic properties of the ligand have been determined on the basis of an ... -
A Tetraferrocenyl-Resorcinarene Cavitand as a Redox-Switchable Host of Ammonium Salts
Wiley (2015-06-10)Tetraannulation of a resorcinarene-octaamino cavitand with ferrocenecarboxaldehyde allows the preparation of a tetrabenzimidazole-resorcinarene cavitand with four ferrocenyl moieties directly linked to the C2 atom of the ... -
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 ... -
First homoleptic MIC and heteroleptic NHC-MIC coordination cages from 1,3,5-triphenylbenzene-bridged tris-MIC and tris-NHC ligands
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 ... -
Fluorescent Pyrene-Based Bis-azole Compounds: Synthesis and Photophysical Analysis
Wiley (2015-06-10)A rational synthetic procedure for the preparation of a series of pyrene-based neutral and dicationic bis-azole compounds is reported. The method allows the tailored design of pyrene-based azoles with different substituents ... -
Immobilization of Pyrene-Tagged Palladium and Ruthenium Complexes onto Reduced Graphene Oxide: An Efficient and Highly Recyclable Catalyst for Hydrodefluorinatio
American Chemical Society (2014-12)The co-immobilization of palladium and ruthenium complexes with pyrene-tagged Nheterocyclic carbene ligands onto reduced grahene oxide allows the formation of a highly efficient catalyst for the hydrodefluorination of a ... -
Post-Modification of the Electronic Properties by Addition of π-Stacking Additives in N-Heterocyclic Carbene Complexes with Extended Polyaromatic Systems
American Chemical Society (2015-03-17)A series of iridium complexes containing phenanthro[4,5-abc]phenazino[11,12-d]imidazol-2-ylidene and acetonaphtho[1,2-b]quinoxaline[11,12-d]imidazol-2-ylidene ligands have been obtained and fully characterized. These ... -
Ruthenium complexes with an N-heterocyclic carbene NNC-pincer ligand: preparation and catalytic properties
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 ... -
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 ...
