A Twisted Tetragold Cyclophane from a Fused BisImidazolindiylidene
Gutiérrez-Blanco, Ana; Ibáñez, Susana; Hahn, Franz Ekkehardt; Poyatos, Macarena; Peris, Eduardo American Chemical Society (2019)The reaction between an angular bis-imidazolidinium salt and [AuCl(SMe)2] allowed the preparation of a discrete digold complex, with a rigid angular bridging bis-imidazolindiylidene ligand. This complex reacts with ... -
Heterometallic complexes, tandem catalysis and catalytic cooperativity
Mata Martínez, Jose A; Hahn, Franz Ekkehardt; Peris, Eduardo The Royal Society of Chemistry (2014)This minireview reports the most recent advances in the use of heterometallic catalysts based on single-frame N-heterocyclic carbene ligands. The article describes the synthetic strategies for the preparation of heterometallic ... -
Hexanuclear cylinder-shaped assemblies of silver and gold from benzene−hexa-N-heterocyclic carbenes
Segarra, Candela; Guisado-Barrios, Gregorio; Hahn, Franz Ekkehardt; Peris, Eduardo American Chemical Society (2014)In this work we describe the preparation of a new benzene–hexaimidazolylidene ligand, which we have coordinated to silver and gold. The new complexes constitute unique examples of cylinder-like macromolecular arrangements, ... -
High-Fidelity, Narcissistic Self-Sorting in the Synthesis of Organometallic Assemblies from Poly-NHC Ligands
Sinha, Narayan; Tan, Tristan T. Y.; Peris, Eduardo; Hahn, Franz Ekkehardt Wiley (2017-05)Highly selective, narcissistic self-sorting has been observed in the one-pot synthesis of three organometallic molecular cylinders of type [M3{L-(NHC)3}2](PF6)3 (M=Ag+, Au+; L=1,3,5-benzene, triphenylamine, or 1,3,5-trip ... -
IrIII/AuI and RhIII/AuI Heterobimetallic Complexes as Catalysts for the Coupling of Nitrobenzene and Benzylic Alcohol
Böhmer, Maximilian; Kampert, Florian; Tan, Tristan; Guisado-Barrios, Gregorio; Peris, Eduardo; Hahn, Franz Ekkehardt American Chemical Society (2018)Two simple bisimidazolium salts derived from m- or p-bisimidazolebenzenes have been used as ligand precursors for the preparation of a series of heterobimetallic RhIII/AuI and IrIII/AuI complexes. All complexes have ... -
Synthesis and Catalytic Applications of Heterobimetallic Carbene Complexes Obtained via Sequential Metalation of Two Bisazolium Salts
Böhmer, Maximilian; Guisado-Barrios, Gregorio; Kampert, Florian; Roelfes, Florian; Tan, Tristan; Peris, Eduardo; Hahn, Franz Ekkehardt American Chemical Society (2019)A simple sequential metalation approach starting from the imidazolium/benzimidazolium salt 4(I)2 yielded the heterobimetallic RhIII/M (M = PdII, IrI , AuI , RuII) complexes [6]− [9]. Alternatively, a symmetrical ... -
Synthesis and Characterization of Poly-NHC-Derived Silver(I) Assemblies and Their Transformation into Poly-Imidazolium Macrocycles
Gutiérrez-Blanco, Ana; Dobbe, Christian B.; Hepp, Alexander; Daniliuc, Constantin G.; Poyatos, Macarena; Hahn, Franz Ekkehardt; Peris, Eduardo Wiley-VCH GmbH (2021-04-22)Three metallosupramolecular assemblies composed of two bis-NHCs and two silver atoms, [4](PF6)2, two tetra-NHCs and foursilver atoms, [7](PF6)4, and two tri-NHCs and three silver atoms[8](BF4)3, have been prepared. Assemblies ... -
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 ... -
Template‐Controlled Synthesis of Polyimidazolium Salts by Multiple [2+2] Cycloaddition Reactions
Dobbe, Christian B.; Gutiérrez-Blanco, Ana; Tan, Tristan T. Y.; Hepp, Alexander; Poyatos, Macarena; Peris, Eduardo; Hahn, Franz Ekkehardt Wiley (2020-09-04)The tetrakisimidazolium salt H4‐2(Br)4, featuring a central benzene linker and 1,2,4,5‐(nBu‐imidazolium‐Ph‐CH=CH‐) substituents reacts with Ag2O in the presence of AgBF4 to yield the tetranuclear, oktakis‐NHC assembly ...
