The melt-phase polymerization of bisphenol A (BPA) and di-Ph carbonate (DPC) catalyzed by alk. metal catalysts produces polycarbonates with high branching, which impairs the product’s properties during weather resistance, ductility, and rheol. The use of an imidazolium-type catalyst can result in a reduced amount of branching relative to the benchmark Cs2CO3 catalyst. Modification of the imidazolium structure, especially by introducing a substitution at the C2 position, definitely improves the catalyst performance in enhancing the catalyst stability and reducing the branching level in the polycarbonate product. For the best catalyst identified (1,3-Ad2-2-Ph-Im-BPA), we have shown that at a DPC/BPA ratio of 1.075 and a catalyst loading of 7 ppm, the specifications can be met at the laboratory scale: polymerization time = 125 min, Mn = 11.0 K, OH = 660 ppm, branching = 460 ppm (∼75% reduction relative to the Cs2CO3 benchmark), and yellowness index = 6.3.

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.
