The solubility of imidazoles in ethers is lower than that in alcohols and decreases with increasing chain length of the ethers . 250285-32-6, formula is C27H37ClN2, Name is 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride. In contrast, the solubility of benzimidazoles in alcohols (C3–C6) is higher than in water and generally decreases with an increase of the alkyl chain length of the alcohols. Reference of 250285-32-6.
Davis, Jacob T.;Martinez, Erin E.;Clark, Kyle J.;Kwon, Doo-Hyun;Talley, Michael R.;Michaelis, David J.;Ess, Daniel H.;Asplund, Matthew C. research published 《 Time-Resolved Ultraviolet-Infrared Experiments Suggest Fe-Cu Dinuclear Arene Borylation Catalyst Can Be Photoactivated》, the research content is summarized as follows. Heterodinuclear complexes with a direct metal-metal bond offer the possibility of unique mechanisms and intermediates. The Cp(CO)2Fe-Cu(IPr) (IPr = N,N-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) heterodinuclear complex 1 is reported to photochem. catalyze arene borylation. To examine possible initial steps of photoinitiated catalysis, the authors synthesized a triethylsilyl-substituted Fe-Cu catalyst derivative 5 that provided cyclohexane solubility to conduct time-resolved UV-IR studies. Time-resolved vibrational spectroscopic measurements suggest that photolysis of 5 stimulates CO dissociation without Fe-Cu metal-metal bond cleavage. UV-IR measurements of 5 with added pinacolborane (HBPin) showed a very similar set of IR bleaches and a new monocarbonyl IR absorbance, and HBPin appears to stabilize the monocarbonyl species. Probably arene borylation catalysis begins with a photochem. step rather than a relatively endothermic thermal-induced cleavage of the Fe-Cu bond, and therefore a new possible catalytic cycle is proposed.

1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride has been used to generate N-heterocyclic carbene catalysts for use in carbonylative cross-coupling of pyridyl halides with aryl boronic acids.
1,3-Bis(2,6-diisopropylphenyl)imidazolium Chloride is an imidazolium salt that is active against all stages of Trypanosoma cruzi and may represent a promising candidate for treatment of Chagas disease.
1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride is an organic compound that is used as a solvent. It was originally synthesized by reacting triethyl orthoformate with 2,6-diisopropylaniline. This reaction formed the corresponding imidazolium salt. The synthesis of this compound was later improved by using ring-opening polymerization of glycolide and furfural. 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride is mainly used to extract estradiol from urine samples in clinical laboratories., 250285-32-6.
