Efficient oxidation of polycyclic aromatic hydrocarbons with H2O2 catalyzed by 5,10,15-triarylcorrolatoiron (IV) chloride in ionic liquids

Direct oxidation of amines to nitriles in the presence of ruthenium-terpyridyl complex immobilized on ILs/SILP

“…12 The reactions reported have used a number of different ionic liquids 5,12 and oxidants. [13][14][15][16] Molecular oxygen and air are cheap and easy to handle agents for several catalytic reactions which have also been applied with ILs. For example, the metal-catalysed selective aerobic oxidation of alcohols to the corresponding aldehydes or ketones using two-component system IJVOIJacac) 2 /DABCO) has been investigated using O 2 in 1-butyl,3-methyl imidazolium hexafluorophosphate IJ[C 4 C 1 im]ijPF 6 ]).…”

Deep Catalytic Oxidative Desulfurization of Model Fuel Based on Modified Iron Porphyrins in Ionic Liquids: Anionic Ligand Effect

“…The structure of [Bmim]­PF 6 was investigated via semi-empirical, ab inito calculation, and the H-bonding of C-2 proton of the imidazolium cation with F of the anion was postulated to exist . When iron porphyrin complex was added to the [Bmim]­PF 6 , the H-bonding of C-2 with the anionic axial ligand would weaken the interaction between the Fe and anionic axial ligand. , Different anionic axial ligands showed different interaction with the center metal, Fe. In general, the interaction of Fe with Cl – is stronger than that of PF 6 – or BF 4 – .…”

“…38 When iron porphyrin complex was added to the [Bmim]PF 6 , the H-bonding of C-2 with the anionic axial ligand would weaken the interaction between the Fe and anionic axial ligand. 37,39 Different anionic axial ligands showed different interaction with the center metal, Fe. In general, the interaction of Fe with Cl − is stronger than that of PF 6 − or BF 4 − .…”

Biomimetic oxidation of pyrene and related aromatic hydrocarbons. Unexpected electron accepting abilities of pyrenequinones

“…Although modest, the isolated yields of pyrenequinones are synthetically useful, and comparable to those recently reported for the catalytic oxidation of smaller PAHs. 35 To the best of our knowledge, this constitutes the first example of Fe-catalyzed C-H oxidation of PAHs.…”
