A chiral magnetic catalyst, L-Co (II) -γ-Fe 2 O 3 , was prepared by complexing a chiral Schiff base ligand containing an ionic liquid to cobalt chloride and then stabilizing the complex on γ-Fe 2 O 3 nanoparticles.The catalyst and ligand were characterized using HNMR, CNMR, CHN, EDX, SEM, UV-Vis, ICP, TGA, VSM, FT-IR, and XRD analyses. Excellent catalytic activity and enantioselectivity were observed in the green epoxidation of alkenes in the presence of TBHP and EtOAc solvent. The catalyst with magnetic separation capability was recovered with a slight decrease in conversion and yield of epoxidation after ve runs.

“…These trials focused on using ILs as co‐catalysts with molybdenum(VI) complexes [29,30] and polyoxometalate [31–33] . Recently, chiral porous poly(ionic liquid)s (CPPILs) supporting chiral salen Mn(III) complex [34] were successfully synthesized and applied electively for catalytic olefin epoxidation.…”

A new chelating task-specific ionic liquid (TSIL), lutidinium-based salicylaldoxime (LSOH), and its square pyramidal vanadyl(II) complex (VO(LSO) 2 ) have been successfully synthesized and structurally characterized using elemental (CHN), spectral, and thermal analyses. The catalytic activity of the lutidinium-salicylaldoxime complex (VO(LSO) 2 ) in the alkene epoxidation reactions was studied under various reaction conditions, such as solvent effect, alkene/oxidant molar ratio, pH, reaction temperature, reaction time, and the catalyst dose. The results demonstrated that the CHCl 3 solvent, 1 : 3 of the cyclohexene/H 2 O 2 ratio, pH 8, temperature of 340 K, and catalyst dose of 0.012 mmol are assigned as the optimum conditions for achieving maximum catalytic activity for VO(LSO) 2 . Moreover, the VO(LSO) 2 complex has the potential for application in the effective and selective epoxidation of alkenes. Notably, under optimal VO(LSO) 2 conditions, cyclic alkenes convert more efficiently to their corresponding epoxides than linear alkenes.
