Insight into the Interactions between Azole-Anion-Based Ionic Liquids and Propargylic Alcohol: Influence on the Carboxylative Cyclization of Propargylic Alcohol with Carbon Dioxide

“…In recent years, spectroscopic techniques have been extensively used to study the hydrogen bonds of solution systems, − and especially IR and NMR spectroscopy have become increasingly popular. − For example, Li et al used IR and NMR spectra to quantitatively calculate the ionicity of protic ILs. Lungwitz and Spange employed 1 H NMR spectroscopy coupled with the Kamlet–Taft equation to determine the hydrogen-bond-accepting (HBA) and -donating (HBD) strengths of ILs with halogeno complex anions.…”

Ammonium-, phosphonium- and sulfonium-based 2-cyanopyrrolidine ionic liquids for carbon dioxide fixation

“…5,29,[31][32][33][34] RTILs, as a rule, possess fine-tunable physical and chemical properties. [35][36][37][38][39][40] The latter makes them attractive for several applications, in which traditional solvents perform poorly.…”

Polarity Prediction of New Ether-Functionalized Ionic Liquids─[COC4mim][Cl] and [COC4mim][Asp]

“…Furthermore, in terms of Fourier transform infrared (FTIR) spectroscopy, excess spectroscopy, and quantum chemical calculations, the microscopic structure and hydrogen bonding interactions between ether-functionalized imidazolium-based ILs and dimethyl sulfoxide (DMSO) were investigated systematically. 13 However, there is a serious shortage of theoretical calculation of the semiempirical method of the polarity so far. The changing trend of the polarity for amino acid ILs was predicted according to the polarity coefficient.…”

“…The results display that [TBA]­[C 12 SO 4 ] presents better catalytic activity and a high capacity of recycles. Furthermore, in terms of Fourier transform infrared (FTIR) spectroscopy, excess spectroscopy, and quantum chemical calculations, the microscopic structure and hydrogen bonding interactions between ether-functionalized imidazolium-based ILs and dimethyl sulfoxide (DMSO) were investigated systematically . However, there is a serious shortage of theoretical calculation of the semiempirical method of the polarity so far.…”
