Abstract

original image

Domain constrained: Polar and nonpolar domains within 1-alkyl-3-methylimidazolium ionic liquids can affect reaction outcomes by pseudo-encapsulation of reactants and this has been explored for a nucleophilic substitution reaction using a cationic substrate and a range of nucleophiles. The significant rate enhancements observed correlate with the concentration of the polar reactants within the ionic liquid's polar domain. ([CnMIM]=1-alkyl-3-methylimidazolium).
