“…The re model of MAG conversion indicated that the optimum conditions were 105 ° [TMA][Arg] load and soybean oil/glycerol ratio 1:2, reaching a maximum yield of 1.26%, higher than the corresponding yield when using conventional catalysts. In an attempt to develop a greener protocol for the cyclization of 2-aminobenzonitrile with CO 2 to yield quinazoline-2,4(1H,3H)-dione, Weng et al [52] investigated the catalytic role of eight biocompatible ILs, synthesized via a neutralization method. The effect of both anion and cation of the corresponding IL was examined, revealing that the IL 1,1,3,3tetramethylguanidinium laevulinate [HTMG][Lev] demonstrated the best results (81% yield), while the reaction's conditions were optimized, including temperature, CO 2 pressure, catalyst amount and time (Scheme 7).…”

Biocompatible Ionic Liquids (Bio-ILs) are a new class of ILs that are task-specifically designed to derive from naturally occurring compounds and/or derivatives thereof, as well as molecules well known for their biocompatibility (e.g., active pharmaceutical ingredients or non-toxic bioactive compounds) in terms of sustainability and biocompatibility. Owing to their remarkable physicochemical properties that can be tailor made to comply with the requirements of each application, Bio-ILs have emerged as novel, efficient and green technology, appropriate for a vast variety of scientific fields. Herein, this review describes the state-of-the-art scientific research regarding the synthesis, characterization and applications of Bio-ILs reported in the literature for the period between 2020 and 2022.

“…The recyclability was examined for the [HTMG][Lae]. Up to five consecutive cycles, there was little loss in the catalytic activity . In addition, Wu and co-workers conducted a computational study on the synthesis of quinazoline-2,4(1 H ,3 H )-diones via cycloaddition of CO 2 with 2-aminobenzoniril catalyzed by [Bmim][OH].…”

CO 2 is an important component of the atmosphere that helps in balancing the Earth's atmospheric temperature and channelizes the food cycles. However, an increase or decrease in the concentration will severely affect the climate. Particularly, the rise in CO 2 levels has immensely contributed to global warming, resulting in elevated atmospheric temperature, altered precipitation patterns, glacier melting, and subsequent rises in sea levels, impacting human well-being. In response, researchers are exploring strategies to capture and convert CO 2 into valuable products, such as methanol, formic acid, and organic compounds. Particularly, the synthesis of organic compounds using CO 2 , like benzimidazole and quinazolines, has a high impact. Benzimidazole, widely used in medicinal chemistry for treating cancer and stomach ulcers, also exhibits antiviral and antifungal properties. Quinazoline derivatives, essential in drugs like prazosin and doxazosin, have applications in treating post-traumatic stress disorder and Alzheimer's disease. These compounds were synthesized mainly using environmentally harmful synthons such as phosgene and potassium cyanide. To address both environmental and health concerns, researchers are delving into the chemical fixation of CO 2 for sustainable and green production. Catalysis emerges as a key principle in green chemistry, with catalysts reducing activation energy and facilitating sustainable processes. This review discusses recent state of the art on the development of various catalysts for conversion of CO 2 to quinazoline and benzimidazole, through various homogeneous and heterogeneous catalysts. Notably, while homogeneous catalysts lack industrial recyclability, heterogeneous catalysts show promise for large-scale implementation. This comprehensive review discusses the mechanistic aspects with DFT studies in understanding the catalysts better. Toward the end, it gives the future scope and aspects on this subject.

“…Liu et al [ 72 ] reports that 1,1,3,3-tetramethylguanidinium laevulinate ([HTMG][Lae]) could catalyze the transformation of CO 2 and o -aminobenzonitriles into quinazoline-2,4(1 H ,3 H )-diones at 70 °C and 10 bar CO 2 without other additives. A feasible reaction mechanism is proposed in Figure 20 .…”

Carbon capture and storage (CCS) and carbon capture and utilization (CCU) are two kinds of strategies to reduce the CO2 concentration in the atmosphere, which is emitted from the burning of fossil fuels and leads to the greenhouse effect. With the unique properties of ionic liquids (ILs), such as low vapor pressures, tunable structures, high solubilities, and high thermal and chemical stabilities, they could be used as solvents and catalysts for CO2 capture and conversion into value-added chemicals. In this critical review, we mainly focus our attention on the tuning IL-based catalysts for CO2 conversion into quinazoline-2,4(1H,3H)-diones from o-aminobenzonitriles during this decade (2012~2022). Due to the importance of basicity and nucleophilicity of catalysts, kinds of ILs with basic anions such as [OH], carboxylates, aprotic heterocyclic anions, etc., for conversion CO2 and o-aminobenzonitriles into quinazoline-2,4(1H,3H)-diones via different catalytic mechanisms, including amino preferential activation, CO2 preferential activation, and simultaneous amino and CO2 activation, are investigated systematically. Finally, future directions and prospects for CO2 conversion by IL-based catalysts are outlined. This review is benefit for academic researchers to obtain an overall understanding of the synthesis of quinazoline-2,4(1H,3H)-diones from CO2 and o-aminobenzonitriles by IL-based catalysts. This work will also open a door to develop novel IL-based catalysts for the conversion of other acid gases such as SO2 and H2S.
