“…In this case, a strong change in the spectrum in the region of valence vibrations of the C–H and C=C bonds of the aromatic ring (3110 and 1500 cm –1 ) indicates a significant rearrangement of the butylimidazole in the π-electron structure. Similar changes in the IR spectrum of N -butylimidazole were observed when imidazole chloride appeared, as described in the work [24].…”

The work is devoted to the chemical modification of a polymer that is promising for the creation of gas separation membranes, aimed at increasing the selectivity with respect to CO2. The introduction of ionic liquids into the structure of poly(1-trimethylsilyl-1-propyne) is realized by a two-step process: bromination of the initial polymer with N-bromosuccinimide and subsequent addition of tertiary amine (N-butylimidazole) to it. Depending on the process conditions, the method allows polymers with different contents of the ionic liquid to be obtained. The obtained polymers show good film-forming properties and thermal stability. Depending on the content of the ionic liquid in the polymer matrix, the resistance to aliphatic alicyclic to the majority of halogenated, as well as aromatic hydrocarbons, increases. With an increase of the ionic liquid content in the polymer, the ideal selectivities of CO2/N2 and CO2/CH4 gas pairs increases while maintaining a high level of permeability.

“…35 The peak of CH 2 stretching vibration showed a red shift from 1468 to 1451 cm −1 , while the peak of CH 3 stretching vibration represented a blue shift from 1374 to 1389 cm −1 . Since the interaction between −N + −H and CuCl 2 − is much weaker than that between −N + −H and Cl-, 36,37 the peaks related to −N + −H (2400−2700 cm −1 ) weakened and showed a blue shift.…”

Diphenhydramine Hydrochloride–CuCl as a New Catalyst for the Synthesis of Tetrahydrocinnolin-5(1H)-ones

et al. 2023

The current study deals with the synthesis and characterization of a novel catalyst made from diphenhydramine hydrochloride and CuCl ([HDPH]Cl−CuCl). The prepared catalyst was thoroughly characterized using various techniques, such as 1 H NMR, Fourier transform-infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis and derivative thermogravimetry. More importantly, the observed hydrogen bond between the components was proven experimentally. The activity of this catalyst was checked in the preparation of some new derivatives of tetrahydrocinnolin-5(1H)ones via a multicomponent reaction between dimedone, aromatic aldehydes, and aryl/alkyl hydrazines in ethanol as a green solvent. Also, for the first time, this new homogeneous catalytic system was effectively used for the preparation of unsymmetric tetrahydrocinnolin-5(1H)-one derivatives as well as mono-and bis-tetrahydrocinnolin-5(1H)-ones from two different aryl aldehydes and dialdehydes, respectively. The effectiveness of this catalyst was further confirmed by the preparation of compounds containing both tetrahydrocinnolin-5(1H)one and benzimidazole moieties from dialdehydes. The one-pot operation, mild conditions, rapid reaction, and high atom economy, along with the recyclability and reusability of the catalyst, are other notable features of this approach.
