Development of Fe(III)-containing ether-functionalized imidazolium ionic liquids for aryl Grignard cross-coupling of alkyl halides

Deep Desulfurization of Fuel Diesels Using Alkyl Sulfate and Nitrate Containing Imidazolium as Ionic Liquids

1-ethyl-3-methylimidazolium ethyl sulfate [Etmim][EtSO4 ],1, 3-dimethylimidazolium methyl sulfate [Mmim][MeSO4 ] and 1-octyl-3-methylimidazolium nitrate [Omim][NO3 ] ionic liquids have been used in thermal oxidative desulfurization of model fuel oils consisting of 500 ppm solutions of benzothiophene (BT) and dibenzothiophene (DBT) in dodecane. The efficiency of sulfur removal from BT and DBT so...

Iron nanoparticles in the coupling of alkyl halides with aryl Grignard reagents.

Iron nanoparticles, either formed in situ stabilized by 1,6-bis(diphenylphosphino)hexane or polyethylene glycol (PEG), or preformed stabilized by PEG, are excellent catalysts for the cross-coupling of aryl Grignard reagents with primary and secondary alkyl halides bearing beta-hydrogens and they also prove effective in a tandem cyclization/cross-coupling reaction.

Iron-Catalyzed Coupling of Aryl Grignard Reagents with Alkyl Halides: A Competitive Hammett Study**

The use of transition-metal catalysis to form new C C bonds is an important tool in organic synthesis. Palladiumand nickel-catalyzed C C bond-forming reactions have been extensively explored and are well understood. The use of iron as the catalyst has gained much less attention, despite the innovative work of Kochi et al. in the 1970s. Recently, several groups have turned their attention toward...

Cross-coupling of alkyl halides with aryl or alkyl Grignards catalyzed by dinuclear Ni(II) complexes containing functionalized tripodal amine-pyrazolyl ligands.

Structurally distinctive dinuclear Ni(II) complexes with furan or thiophene tethered amine-pyrazolyl tripodal hybrid ligands have been synthesized and crystallographically characterized. All complexes are catalytically active towards cross-coupling of aryl/alkyl Grignard reagents with β-H containing alkyl halides at room temperature in the presence of N,N,N',N'-tetramethylethylenediamine (TMEDA...
