Zhu, Xinrui published the artcileOne-step preparation of ammonium-specified pyrazolium ionic liquids unveil the more popular pathway for the CO2 fixation: Integrated experimental and theoretical studies, COA of Formula: C4H6N2, the publication is Journal of Molecular Liquids (2021), 115435, database is CAplus.
Amino-specified pyrazolium ionic liquid (APEPzBr) is synthesized by two steps. It is interesting that the product of the first step ([EPzPNH3]Br2) could also catalyze the coupling reaction of carbon dioxide and epoxides under 70°C along with 0.5 MPa CO2 pressure, which is even more benign than APEPzBr. It is attributed to the strong ability of [EPzPNH3]Br2 to absorb CO2 along with robust electrophilic activation, which is testified by d. functional theory and 13C NMR measurement. The difference between [EPzPNH3]Br2 and APEPzBr is further elucidated by electron localization function (ELF) and atoms in mols. (AIM).
