(Bis{2-[3-(2,4,6-trimethylbenzyl)imidazolin-2-yliden-1-yl-κC2]-4-methylphenyl}amido-κN)chloridopalladium(II)

Acta Crystallographica Section E, 2010
The coordination geometry about the Pd centre in the title compound, [Pd(C40H42N5)Cl], is approximately square-planar. The CNC pincer-type N-heterocyclic carbene ligand binds to the Pd atom in a tridentate fashion by the amido N atom and the two carbene ...

Experimental and theoretical investigations on the high-electron donor character of pyrido-annelated N-heterocyclic carbenes

Beilstein Journal of Organic Chemistry, 2016
Rh(CO)2Cl(NHC) complexes of dipyrido-annelated N-heterocyclic carbenes were prepared. From the C–H coupling constant of the respective imidazolium salts and the N–C–N angle of the N-heterocyclic carbene (NHC), a weaker σ-donor character than that of ...

The Potential of N-Heterocyclic Carbene Complexes as Components for Electronically Active Materials

CHIMIA, 2010
The application of N-heterocyclic carbene complexes as active sites in materials other than catalysis has been remarkably scarce. Inspired by the – often misleading – 'carbene' label, which implies a substantial degree of M=C ?

Highly Robust but Surface-Active: N-Heterocyclic Carbene-Stabilized Au25 Nanocluster as a Homogeneous Catalyst [PDF]

, 2019
Surface organic ligands play a critical role in stabilizing atomically precise metal nanoclusters in solutions. However, it is still challenging to prepare highly robust ligated metal nanoclusters that are surface-active for liquid-phase ...

Direct Synthesis of N‐Heterocyclic Carbene‐Stabilized Copper Nanoparticles from an N‐Heterocyclic Carbene–Borane [PDF]

Chemistry – A European Journal, 2019
AbstractN‐Heterocyclic carbene (NHC)‐stabilized copper nanoparticles (NPs) were synthesized from an NHC–borane adduct and mesitylcopper(I) under thermal conditions (refluxing toluene for 2.5 h). NPs with a size distribution of 11.6±1.8 nm were obtained. The interaction between Cu NPs and NHC ligands was probed by X‐ray photoelectron spectroscopy, which

N-Heterocyclic Carbene Coinage Metal Complexes Containing Naphthalimide Chromophore: Design, Structure, and Photophysical Properties

Inorganics, 2017
A series of novel N-heterocyclic carbene coinage metal complexes containing a naphthalimide (NI) chromophore has been prepared and fully characterized. Two types of molecules are described those where the NI unit is directly attached to the carbene unit ...

Photodynamics of Fe complexes: Variation with number of NHC functions [PDF]

EPJ Web of Conferences, 2019
Ultrafast spectroscopy on a series of Fe(II) complexes finds an increase of the 3MLCT lifetime with increasing number of N-heterocyclic carbene (NHC) donor functions revealing a promising route for the design of Fe photosensitizers.

Atomically precise ultrasmall copper cluster for room-temperature highly regioselective dehydrogenative coupling

Nature Communications, 2023
Three-component dehydrogenative coupling reactions represent important and practical methodologies for forging new C–N bonds and C–C bonds. Achieving highly all-in-one dehydrogenative coupling functionalization by a single catalytic system remains a ...

1,3-Bis(4-methylbenzyl)imidazol-2-ylidene silver(I) chloride catalyzed carboxylative coupling of terminal alkynes, butyl iodide and carbon dioxide

Journal of Saudi Chemical Society, 2017
The N-heterocyclic carbene silver(I) complex 1,3-bis(4-methylbenzyl)imidazol-2-ylidene silver chloride was applied as the effective catalyst for the three-component carboxylative coupling of terminal alkynes, butyl iodide and carbon dioxide. The reaction
