Another silver complex of 1,3-dibenzylimidazol-2-ylidene: Solution and solid-state structures

The reaction of 1,3-dibenzylimidazolium bromide (Bn2Im · HBr) with silver(I) oxide yields the dinuclear compound {(Bn2Im)AgBr}2 as determined with X-ray crystallography. The structure turned out to differ significantly fro

MOF Encapsulating N-Heterocyclic Carbene-Ligated Copper Single-Atom Site Catalyst towards Efficient Methane Electrosynthesis

The exploitation of highly efficient carbon dioxide reduction (CO2RR) electrocatalyst for methane (CH4) electrosynthesis has attracted great attention for the intermittent renewable electricity storage but remains challenging. Here,

DISSOLUTION OF CELLULOSE IN IONIC LIQUIDS

The present invention includes a method for dissolving cellulose comprising dissolving cellulose in an ionic liquid and a co-solvent, wherein the ionic liquid is an imidazolium-based ionic liquid with, e.g., a halide or acetate as the anion.

Synthesis and electrochemical evaluation of 2-substituted imidazolium salts

Herein, we report the synthesis, electrochemical, and computational evaluation of six 2-substituted imidazolium bromides and six 2-substituted imidazolium triflates. All final compounds were obtained in 2 or fewer synthetic steps from inexpensive starting

Small “Yaw” Angles, Large “Bite” Angles and an Electron-Rich Metal: Revealing a Stereoelectronic Synergy To Enhance Hydride-Transfer Activity

Cyclometalated complexes are an important class of (pre)catalysts in many reactions including hydride transfer. The ring size of such complexes could therefore be a relevant aspect to consider while modulating their catalytic activity. However, any correl

Unraveling the synthesis of homoleptic [Ag(N, N -diaryl-NHC)2]Y (Y = BF4, PF6) complexes by ball-milling

A user-friendly and general mechanochemical method was developed to access rarely described NHC (N-heterocyclic carbene) silver(i) complexes featuring N,N-diarylimidazol(idin)ene ligands and non-coordinating tetrafluoroborate or hexafluorophosphate counter anions. Comparison with syntheses in solution clearly demonstrated the superiority of the ball-milling conditions.

Acceptorless Dehydrogenative Oxidation of Secondary Alcohols Catalysed by Cp*IrIII–NHC Complexes

A series of new IrIIIcomplexes with carbene ligands that contain a range of benzyl wingtip groups have been prepared and fully characterised by NMR spectroscopy, HRMS, elemental analysis and X-ray diffraction. All the complexes were active in the acceptorless dehydrogenation of alcohol substrates in 2,2,2-trifluoroethanol to give the corresponding carbonyl compounds. The most active complex bore an electron-rich carbene ligand; this complex was used to catalyse the highly efficient and chemoselective dehydrogenation of a wide range of secondary alcohols to their respective ketones, with turnover numbers up to 1660. Mechanistic studies suggested that the turnover of the dehydrogenation reaction is limited by the H2-formation step.

Iridium(I) N-Heterocyclic Carbene (NHC)/Phosphine Catalysts for Mild and Chemoselective Hydrogenation Processes

The directed chemoselective hydrogenation of olefins has been established by using iridium(I) catalysts, which feature a tuned NHC/phosphine ligand combination. This selective reduction process has been demonstrated in a wide array of solvents, including more environmentally acceptable media, also allowing further refinement of hydrogenation selectivity.

Expedient Mechanosynthesis of N,N-Dialkyl Imidazoliums and Silver(I)-Carbene Complexes in a Ball-Mill

The absence of solvent, associated with intensive mechanical agitation, allowed the first mechanosynthesis of high-value silver(I)-carbene complexes and the corresponding N,N-dialkylimidazolium precursors. This procedure gave outstanding results in terms of yield and reaction time, when compared to solution-based conditions previously described in literature, and was generalized to unprecedented compounds. Silver(I)-carbene complexes could either be obtained from N,N-dialkylimidazolium salts or directly from imidazole and alkyl halides in a one-pot two-step procedure without isolating the imidazolium intermediate. Additionally, an efficient one-pot three-step sequence, including imidazole alkylation, silver metalation, and transmetalation is reported. You only hit twice! Solvent-free mechanochemical conditions enabled the rapid synthesis of high-value N,N-dialkyl-substituted NHC silver(I) complexes and the corresponding N,N-dialkylimidazolium precursors. Mechano-metalation and transmetalation are performed in a highly user- and eco-friendly approach. By using this strategy, up to three consecutive chemical steps, leading to organometallic complexes, could be performed in a ball-mill with high efficiency.
