Arynes are a unique class of intermediates used in synthetic organic chemistry, and research interest has been intensely focused on their peculiar reactivities. Arynes have been researched for almost a century. However, difficulties in monitoring these reactive species, as well as difficulties in creating synthetically viable techniques for their synthesis and trapping, have restricted their application. A key tactic for achieving the racemic and enantiopure total synthesis of a broad variety of natural compounds or their structural derivatives. The chemistry of arynes has advanced significantly over the past thirty years, particularly in the field of transition metal carbon- carbon and carbon-heteroatom bond-forming mechanisms. The field’s fast growth is largely attributable to the development of mild aryne production processes. To create a natural product with complex organic molecules, the role of aryne intermediates was non-replaceable. These organic substances are often used in medicine, therapies, or as raw material for the synthesis of other substances. Moreover, they may perform important biological tasks. There are numerous methods for synthesizing natural compounds including total synthesis, semi-synthesis, and biosynthesis. Total synthesis is the process of creating natural products entirely chemically from basic precursors as well as it can be produced in large quantities and can reveal information about its biological activity. One of the developments in Arynes’ chemistry is the chemical rearrangements brought about by this electrophilic intermediate. It is not feasible to use conventional methods in a single step. This review article discusses how arynes are used to create natural products. Arynes has a wide range of functionality in the field of scientific research. The evolution of this method has made a tremendous change in the total synthesis of natural products. Benzynes enabled creative synthesis in mild conditions. The transformation has expanded to investigate various reaction classes such as nucleophilic addition, (4+2), and (2+2) cycloaddition strategies and metal-catalyzed reactions are shown and explained in this article. This review will provide an idea about how the arynes act as an intermediate in those reaction mechanisms and enlighten the scope of these aryne intermediate.

“…Therefore, it is crucial to manage and minimize CO 2 emissions, address the greenhouse effect, and combat global warming by developing an effective CO 2 capture technology for coal-fired power plants. Currently, carbon capture and storage (CCS) and carbon capture and utilization (CCU) 4 are considered the primary CO 2 emission reduction, capture, and resource utilization paths. However, a novel form of integrated CO 2 capture and utilization (ICCU) 5 technology that provides a unique cost-effective strategy for sustainable CO 2 management has been proposed recently.…”

To investigate intermolecular interactions between three different structures of butanol (n-butanol, 2-butanol, or iso-butanol) and 1,2-propanediamine (1,2-PDA), the density (ρ) and viscosity (η) of these butanol isomers + 1,2-PDA binary systems were determined in the temperature range of 298.15−318.15 K at a pressure of 100.5 kPa. Based on these data, the activation thermodynamic parameters and excess properties, including excess molar volume (V m E ), partial molar volume (V̅ ), apparent molar volume (V ϕ ), coefficient of thermal expansion (a p ), viscosity deviation (Δη), activation enthalpy change (ΔH*), activation entropy change (ΔS*), Gibbs energy of activation of viscous flow (ΔG*), and the excess Gibbs energy of activation of viscous flow activation Gibbs energy (ΔG* E ) were systemically calculated. Subsequently, the influence of test temperatures on the physical characteristics of the binary systems was thoroughly investigated. Several semiempirical models were used to match the experimental density and viscosity values, and the values of V m E , Δη, and ΔG* E were calculated using the Redlich−Kistre equation. The intermolecular hydrogen bonds (HBs) in the three binary systems were analyzed by Raman and ultraviolet spectroscopy. Finally, the form of HBs and the van der Waals effects in the butanol isomer + 1,2-PDA binary systems were confirmed through computational studies.

“…The global greenhouse effect has been exacerbated by significant quantities of CO 2 emissions resulting from the use of fossil fuels . Carbon capture and utilization (CCU) is an efficient way to reduce CO 2 emissions and an important part of achieving the goal of carbon neutrality. − The conversion of CO 2 into chemicals or fuels is currently the dominant route, and methanol synthesis is considered to be one of the most promising routes, because methanol is not only a chemical product but also a transportation fuel. , In addition, as a key product of the coal-to-olefin process, methanol reduces the external dependence on oil as well as indirectly contributes to the rapid development of the coal chemical industry . Meanwhile, the CO 2 -to-methanol (CTM) process can be used as a substitute for gasoline and diesel fuel or as a feedstock for fuel cells, − which is in line with the concept of the “methanol economy” proposed by Nobel Prize winner Olah …”

The CO 2 -to-methanol (CTM) process can realize the recycling of carbon resources and mitigate the global greenhouse effect. However, the low CO 2 conversion rate is a consequence of the thermodynamic equilibrium, which restricts the direct hydrogenation of CO 2 to methanol (CTM I ). Furthermore, there exists a state of kinetic competition between the reaction that produces methanol and the reaction that reverses the water−gas shift, which leads to the low selectivity of methanol.To solve these problems, a new process of indirect hydrogenation of CO 2 to methanol and the coproduction of ethylene glycol (CTM II ) was proposed in this paper. The steady state modeling, energy integration, and technoeconomic evaluation of the new process were carried out. It was found that the carbon and hydrogen utilization rates of the CTM II process were 98.95% and 98.63%, respectively, corresponding to increases of 2.99% and 34.21%, respectively, compared to those of the CTM I process. The selectivities of methanol and ethylene glycol in the CTM II process are 47.44% and 52.56%, respectively. Under the current economic conditions (0.35 CNY/kWh electricity, 1.8 CNY/m 3 natural gas, 5000 CNY/t ethylene glycol, and 17.5 CNY/kg H 2 ), the production cost of the CTM II process was 2572 CNY/t-CH 3 OH, 38.82% lower than that of the CTM I process. The net present value was calculated, and a sensitivity analysis of the relationship between hydrogen and production costs was performed. When the H 2 price dropped to 13.6 CNY/kg, the product cost of CTM II could compete with that of the coal-to-methanol process, showing great economic potential for the future. This study presented a novel approach for the utilization of CO 2 resources and broadened the path for green and low-carbon production of methanol.
