Facile Construction of Carboxyl-Functionalized Ionic Polymer towards Synergistic Catalytic Cycloaddition of Carbon Dioxide into Cyclic Carbonates

International Journal of Molecular Sciences, Год журнала: 2022, Номер 23(18), С. 10879 - 10879

Опубликована: Сен. 17, 2022

The development of bifunctional ionic polymers as heterogeneous catalysts for effective, cocatalyst- and metal-free cycloaddition carbon dioxide into cyclic carbonates has attracted increasing attention. However, facile fabrication such having high numbers active sites, suitable types hydrogen bond donors (HBDs), controlled spatial positions dual sites remains a challenging task. Herein, imidazolium-based with hydroxyl/carboxyl groups density were facilely prepared by one-pot quaternization reaction. Catalytic evaluation demonstrated that the presence HBDs (hydroxyl or carboxyl) could enhance catalytic activities significantly toward CO2 Among catalysts, carboxyl-functionalized polymer (PIMBr-COOH) displayed highest activity (94% yield) in benchmark reaction epichlorohydrin, which was higher than hydroxyl-functionalized (PIMBr-OH, 76% yield), far exceeded without (PIMBr, 54% yield). Furthermore, PIMBr-COOH good recyclability wide substrate tolerance. Under ambient pressure, number epoxides smoothly cycloadded carbonates. Additionally, functional theory (DFT) calculation verified formation strong bonds between epoxide polymers. possible mechanism proposed based on synergistic effect carboxyl Br- functionalities. Thus, facile, synthetic strategy construction developed fixation.

Merrifield Resin Supported Ionic Liquids: Catalytic Applications in Organic Synthesis

Current Organic Chemistry, Год журнала: 2023, Номер 27(2), С. 130 - 152

Опубликована: Янв. 1, 2023

Abstract: Ever since their discovery, Ionic Liquids have raised great interest in organic transformations ranging from solvents to catalytic entities. These belong a class of nonmolecular compounds composed ions having curiously low melting points. In the last few years, Supported drawn attention researchers and chemists due advantages over homogeneous catalysis. The most commonly used support for immobilized ionic liquids is polymeric. Due its efficient recovery, reusability chemical inertness, Merrifield resin can be considered an excellent solid liquids. present review summarizes synthesis application Resin (MRSILs). MRSILs synthesized by immobilization amines like ammonium, choline, imidazolium, DABCO, DMAP, pyridine, many other functionalized precursors. Additionally, these play incredible role field catalysis, where both metal-free metal-containing are embodied as catalyst.

Abstract Malaria remains a severe infectious disease caused by Plasmodium parasites among the primarily afflicting impoverished populations. According to World Health Organization (WHO) report, there were an estimated 247 million malarial cases globally, resulting in approximately 6,19,000 fatalities. Particularly prevalent tropical and subtropical regions, development of drug resistance has exacerbated this public health challenge. Consequently, been concrete effort explore novel compounds with anti‐malarial properties. In continuation our previous works, review focuses on heterocyclic documented 2021 2022, including artemisinin, benzimidazole, benzofuran, β‐lactam, coumarin, furan, indole, morpholine, piperazine, pyrimidine, quinoline, triazole, etc. highlighting their efficacy, structural characteristics, vitro vivo activities, other relevant aspects for broad interest medicinal chemists working design agents.
