Design of Reaction Media for Nucleophilic Substitution Reactions by Using a Catalytic Amount of an Amphiphilic Imidazolium Salt in Water
摘要:
Molecules of an amphiphilic imidazolium salt assemble in water to form a hydrophobic membrane including an interface consisting of ammonium species. Such an interface works as a reaction medium like an ionic liquid. We used the medium for nucleophilic substitution reactions between alkyl halides and anionic nucleophiles. This procedure allowed the reactions to proceed efficiently in water without any organic solvent.

A composition including an ionic liquid alkyl ammonium salt (e.g., tetraalkylammonium cation and bis(trifluoromethanesulfonyl)imide anion) or an ionic liquid imidazolium salt (e.g., L3-dialkyliniidazoiiimi cation and bis(trifluoromethanesulfonyl)imide anion), that have a structure sufficient to exhibit at least partial solubility in one or more Group I-V base stocks. The disclosure also relates to a lubricating oil base stock and lubricating oil containing the composition, a multifunctional functional fluid containing the composition, and a method for improving solubility of an ionic liquid in a lubricating oil by using as the lubricating oil a formulated oil including a lubricating oil base stock as a major component, and an ionic liquid alkylammomum salt cobase stock, or an ionic liquid imidazolium salt cobase stock, as a minor component.
