A FeCl3-based ionic liquid for the oxidation of anthracene to anthraquinone

From Paramagnetic to Superparamagnetic Ionic Liquid/Poly(ionic liquid): The Effect of π–π Stacking Interaction

“…Magnetic ionic liquids (MILs), which are composed of organic cations and magnetic anions, have been widely studied because of their unique chemical and physical properties, for example, low vapor pressure, thermal stability, low melting point, and good solubility. − Recently, poly­(magnetic ionic liquid)­s (PMILs), which usually bear an MIL unit in the side group of the repeating unit, have been explored as new magnetic polymers. , MILs and PMILs show potential applications in magnetic surfactants, − catalysts, substantial analysis, magnetic separation, , biomedical science, − and so on. − Compared with the hybridized magnetic polymers, the MILs and PMILs were meltable and soluble, which were profitable in processing. The magnetic properties of MILs and PMILs was resulted from the magnetic anions, which contain high spin orbital 3d electrons.…”

Acid‐Functionalised Magnetic Ionic Liquid [AcMIm]FeCl4 as Catalyst for Oxidative Hydroxylation of Arylboronic Acids and Regioselective Friedel–Crafts Acylation

“…In addition, H 2 O 2treated [AcMIm]FeCl 4 exhibits am ultiple EPR spectrum with al ower g value (g = 1.45;F igure S7 in the Supporting Information);t his may indicatet he presence of ah ydroxyl free radical, hydroperoxyl radical or triplet oxygen diradical (oxene). [51][52][53][54][55] Also, the small and sharp peak in the EPR spectrum with a g value of approximately 4.1 signifies the presenceo fh igh-spin iron species( Figure S7 in the Supporting Information). [54] Based on the above observations, we have proposed aplausible reaction mechanism for the [AcMIm]FeCl 4 -promoted oxidativeh ydroxylation of arylboronic acids (Scheme 3).…”

Ionic Liquids in Selective Oxidation: Catalysts and Solvents

“…The oxidation activities of TS and BT were higher than that of DBT, being different from those reported with solid−oil−water three-phase oxidation using H 2 O 2 as oxidant, which may be due to the reaction occurring in a gas−solid−oil triphasic system. Zhang et al 90 reported that cobalt phthalocyanines (CoPc(Cl) n ) exhibited effective activity for the oxidative desulfurization of DBT using air as oxidant in IL at room temperature, and the activity of cobalt phthalocyanines increases in the order of CoPc(Cl) 4 < CoPc(Cl) 8 < CoPc(Cl) 12 < CoPc(Cl) 16 . The removal ratio could reach 90% using CoPc(Cl) 16 catalyst.…”
