Ionic liquid as an efficient promoting medium for two-phase nucleophilic displacement reactions

The Phosphorus Aspects of Green Chemistry: the Use of Quaternary Phosphonium Salts and 1,3-Dialkylimidazolium Hexafluorophosphates in Organic Synthesis

“…The reaction of alkyl halides with potassium cyanide [120] and sodium azide [121] 6 ] and aqueous-dichloromethane biphasic system (Scheme 64) [112]. The cyanide substitution of aryl halides was promoted by microwave irradiation (Scheme 65) [122].…”

Kinetic Study on the Catalytic Effect of Ionic Liquids on the Polymerization of Methyl Methacrylate Co‐initiated by Imine Bases

“…The use of room temperature ILs has gained high interest in academia and industry in the last decades due to their use as coreactants and catalysts in organic and inorganic chemistry as well as in poly mer and material science. [2][3][4][5][6][7][8][9][10][11][12][13] It is well established that ILs have a strong effect on the molecular weight distribution of the products as well as on the rate of conventional radical polymerizations such as the MMA polymerization. [13][14][15] However, there are a lot of speculative interpretations and poorly understand effects, which are critically refl ected by Puttik et al [ 11 ] Especially, the radical-protecting effect of ILs upon the propagating species is of importance because it opens a way to achieve longliving radicals and controlled radical polymerization.…”

Imidazolium salt assisted hydrolysis of 1-chloro-2,2,2-trifluoroethane

“…Recently, the use of ionic liquids such as 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF 6 ]) has been demonstrated as catalyst and solvent for the conversion of an alcohol to an alkyl halide [7,8]. With a hope that ionic liquids could also find a role in promoting the hydrolysis reaction of alkyl halides containing highly electron withdrawing functional groups like CF 3 , various ionic liquids were prepared and tested for their effects on the hydrolysis of CF 3 CH 2 Cl.…”
