Summary: Four carbonyl rhodium polyether guanidinium ionic liquids were synthesized via ion exchange strategy, and their catalytic performance in asymmetric hydroformylation of styrene was investigated. The unique solubility properties of these ionic liquids led to the establishment of a highly effective homogeneous catalysis-biphasic separation system for the reaction. The reusability of the system was demonstrated up to four times without significant decrease in activity, showcasing potential for practical applications.

Summary: A new strategy for direct access to fully substituted polycyclic imidazolium salts using alpha-enaminones and proline as the reagents is reported. This open-flask operation is a catalyst-, metal-, and Lewis acid-free green process, which does not require an ion-exchange step. It can produce good yields with minimal formation of side products, and is not limited to aryl substituents.

Summary: Single-atom Rh catalysts show superior activity in olefins hydroformylation but limited success in regioselectivity control. By developing a Rh1 single-atom catalyst with nanodiamond as support, the catalyst achieved good to excellent regioselectivities in hydroformylation of arylethylenes, comparable to homogeneous counterparts. The coordination interaction between Rh-1 and surface phosphorus species was clarified by P-31 solid-state NMR and X-ray absorption spectroscopy.

Summary: The use of biobased and bioactive compounds has led to the development of sustainable extraction and purification processes using ionic liquids. In this study, six novel analogues of glycine-betaine ILs (AGB-ILs) were investigated for their potential use in IL-based ABS. The synthesized ILs showed relatively low ecotoxicity and good thermal stability. The extraction efficiency of furfural using AGB-ILs-based ABS was found to be up to 98%, suggesting the potential of these novel ABS for separation of bioactive compounds.

Summary: This paper describes the corrosion inhibiting action of four new imidazolium-derived ionic liquids (ILs). Various analytical techniques were used to confirm their molecular formula and characterize their adsorption behavior on a steel substrate. Results showed that these ILs exhibited effective corrosion suppression and adsorbed onto the steel surface through physi-chemisorption. SEM/EDX and FTIR analysis further supported the adsorption process of the ILs.

Summary: Knowledge of frontier orbital energies, such as HOMO and LUMO, is crucial for studying stability, corrosion inhibition potential, and reactivity of compounds. Density functional theory (DFT) calculations provide an approach to estimate these energies, but it becomes computationally intensive for large-scale screening. In this article, a machine learning model based on extreme gradient boosting is developed to predict HOMO and LUMO energies, resulting in significantly reduced computational time.

Summary: The aerobic oxidation of lignin model 2-phenoxyacetophenone (2-PAP) in cooperative ionic liquid mixtures (CoILs) with [C(2)C(1)im]OAc and [B(Z)C(1)im]NTf2 was investigated. The CoILs showed higher conversion and product yields compared to pure ILs, indicating the cooperative effects of the two ILs. [C(2)C(1)im]OAc promoted the catalytic cleavage of aryl-ether bonds and solvation, while [B(Z)C(1)im]NTf2 induced the formation of alkyl radicals and enhanced the product selectivity.

Summary: The self-assembly behavior of ionic liquids in aqueous solution was studied through molecular dynamics simulations, revealing the dominant role of interactions between tail groups in stabilizing vesicles and the influence of membrane thickness and alkyl chain arrangement on vesicle permeability. The interdigitated structure of tail groups reduced water exchange rate, while the orientation of the imidazolium ring promoted water molecules approaching hydrophobic regions. These findings suggest the potential for obtaining vesicles with excellent permeability properties by screening the hydrophilic and hydrophobic properties of ILs for applications in separation and drug delivery processes.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
