Solutions of weakly coordinating ionic liquids (ILs) in alkyl carbonates are gaining growing attention, as the latter “green” solvents with high solvation power, but phase behavior and structure ILs organic polar still poorly understood. Here, we study interactions nanoscale 1‑butyl‑3-methylimidazolium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, [BMIm][BARF], three symmetrical carbonate inc...

The reaction of the benzene derived trisimidazolium salt [1](PF(6))(3) with [PdCl(allyl)](2) gave complex [2](PF(6))(3) featuring three Pd(allyl) moieties sandwiched between two tricarbene ligands, whereas the reaction of [1](PF(6))(3) with [M(Cp*)(Cl)(2)](2) (M = Ir, Rh) resulted in the formation of dinuclear M(III) complexes [3]PF(6) (M = Ir) and [4]PF(6) (M = Rh) where each metal center is c...

The title salt, C13H11N2O2 (+)·C6H2N3O7 (-), is the unexpected product of a domino reaction of 3-cyano-methyl-1-methyl-imidazolium chloride with salicylic aldehyde in the presence of picric acid. In the cation, the 1H-imidazole ring is twisted by 63.2 (1)° from the 2H-chromen plane. In the crystal, cations and anions are alternately stacked along the a axis through π-π stacking inter-actions be...

A detailed (1)H-NMR study of the anion binding properties of the 2-iodo-imidazolium receptor 1 in DMSO allows to fully attribute the observed affinities to strong charge-assisted C-I···X(-) halogen bonding (XB). Stronger binding was observed for oxoanions over halides. Phosphate, in particular, binds to 1 with an association constant of ca. 10(3) M(-1), which is particularly high for a single X...

Abstract Isolation of E -1,2-bis(4-bromophenyl)-1,2-diphenyl-ethylene from the E/Z isomer mixture obtained by a McMurry coupling reaction and this with imidazole followed N -alkylation n BuBr anion exchange yielded bisimidazolium tetraphenylethylene (TPE) derivative H 2 - 1 (PF 6 ) . The Ag O di-nuclear metallarectangle [Ag ( ](PF where two bis-NHC donors bridge silver atoms. Irradiation leads ...

By employing (1)H NMR spectroscopy and molecular simulations, we provide an explanation for recent observations that the aqueous solubilities of ionic liquids exhibit salting-out to salting-in regimes upon addition of distinct inorganic salt ions. Using a typical ionic liquid [1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide], we observed the existence of preferential specific inte...

Herein we describe the synthesis of gold nanoparticles (Au-NPs) in presence of sulphonated imidazolium salts [1,3-bis(2,6-diisopropyl-4-sodiumsulfonatophenyl)imidazolium (L1), 1-mesityl-3-(3-sulfonatopropyl)imidazolium (L2) and 1-(3-sulfonatopropyl)imidazolium (L3)] in water and in a confinement environment created by reverse micelles (RMs). The Au-NPs were characterized-with an excellent agree...
