A novel synthetic route leading to N-heterocyclic carbene copper complexes has been developed by using air-stable and commercially available copper(I) oxide and imidazolium salts starting materials.

A series of 1-alkyl-3-methylimidazolium hexafluorocomplex salts (C(x)MImAF(6), x = 14, 16 and 18, A = P, As, Sb, Nb and Ta) have been characterized by thermal analysis, X-ray diffraction and polarized optical microscopy. A liquid crystalline mesophase is observed for all the C(16)MIm and C(18)MIm salts. The C(14)MIm(+) cation gives a liquid crystalline mesophase only with PF(6)(-). The temperat...

We report the synthesis of original imidazolium salts with tetraphenylborate anion and their use as precursors for boron, nitrogen co-doped carbon materials. In addition to benefic effet tetraphenylborate...

The Ag(I) and hemilabile Pd(II) carbene complexes obtained from novel thioether-functionalized imidazolium salts synthesised in one-step illustrate the diversity of coordination modes of these new S, C(NHC) ligands.

Novel salts based on 1,3-dibutyl-4-(2-hydroxyphenyl)-1H-imidazolium bromide or iodide have been developed as bifunctional organocatalysts for the cycloaddition reaction of epoxides and isocyanates to form 3,4- 3,5-disubstituted oxazolidin-2-ones. The molecular structure these compounds was determined spectroscopically confirmed by X-ray diffraction analysis. Imidazolium were screened catalysts ...

Formation of anionic ditopic N-heterocyclic dicarbene having two linking phosphorus centers – one neutral and is presented, along with a first glimpse on the coordination chemistry bis(imidazolium) salts.

A general approach for the synthesis of bis(imidazolium) dichloride salts from imidazoles and dichloroalkanes is reported. Typical limitations this reaction formation methylene-bridge...

Mechanical forces induced by ball-milling agitation enabled the highly efficient and widely applicable synthesis of Cu–carbene complexes from N,N-diaryl-imidazolium salts and metallic copper. The required amount of gaseous dioxygen and insoluble copper could be reduced down to stoichiometric quantities, while reaction rates clearly outperformed those obtained in solution. Utilisation of Cu(0) a...

A series of novel imidazolium salts bearing hydrophilic tetraethylene glycol (TEG) and/or hydrophobic long-chain alkyl (n-C12) functionalities, which are precursors for desired N-heterocyclic carbene (NHC) ligands, were synthesized and characterized. Rh(I)-NHC complexes were prepared in good yields by the silver carbene transfer method with NHC-Ag species derived from the imidazolium salts. The...
