The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate( cas:286014-53-7 ) is researched.Electric Literature of C21H25BF4N2.Alcalde, Ermitas; Dinares, Immaculada; Ibanez, Anna; Mesquida, Neus published the article 《A simple halide-to-anion exchange method for heteroaromatic salts and ionic liquids》 about this compound( cas:286014-53-7 ) in Molecules. Keywords: halide anion exchange heteroaromatic salt ionic liquid. Let’s learn more about this compound (cas:286014-53-7).
A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A- form) in non-aqueous media. The anion loading of the AER (OH- form) was examined using two different anion sources, acids or ammonium salts and changing the polarity of the solvents. The AER (A- form) method in organic solvents was then applied to several quaternary heteroaromatic salts and ILs and the anion exchange proceeded in excellent to quant. yields, concomitantly removing halide impurities. Relying on the hydrophobicity of the targeted ion pair for the counter anion swap, organic solvents with variable polarity were used, such as CH3OH, CH3CN and the dipolar nonhydroxylic solvent mixture CH3CN:CH2Cl2 (3:7) and the anion exchange was equally successful with both lipophilic cations and anions. The synthesis of the target compounds was achieved in good yield and title compound and title compounds thus formed included an ibuprofen derivative (I), a choline derivative 2-hydroxy-N,N,N-trimethylethanaminium (2S)-2-hydroxypropanoate (1:1), etc., N-decyl-N,N-dimethyl-1-decanaminium (αS)-α-hydroxybenzeneacetate (1:1) (II).
《A simple halide-to-anion exchange method for heteroaromatic salts and ionic liquids》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(1,3-Dimesityl-1H-imidazol-3-ium tetrafluoroborate)Electric Literature of C21H25BF4N2.
