Physicochemical characterization of new sulfonate and sulfate ammonium ionic liquids

In this work we describe the synthesis and thermal properties of nine new salts derived from ammonium that incorporate alkanesulfonate and alkanesulfate anions. Their structures were confirmed by 1H and 13C NMR and HRMS-ESI. Their thermal properties were determined by differential scanning calorimetry (DSC). Three of the synthesized salts have been shown to be room temperature ionic liquids: N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium butanesulfonate, N-ethyl-N,N-dimethylbutylammonium ethylsulfate, and N-ethyl-N-(2-hydroxyethyl)-N,N-dimethylammonium ethylsulfate. Experimental densities, speeds of sound, dynamic viscosities, and refractive indices of these three ionic liquids were measured at T = 298.15 K.

Foldamers as reactive sieves: Reactivity as a probe of conformational flexibility

A series of m-phenyleneethynylene (mPE) oligomers modified with a dimethylaminopyridine (DMAP) unit were treated with methyl sulfonates of varying sizes and shapes, and the relative reactivities were measured by UV spectrophotometry. Using a small-molecule DMAP analogue as a reference, each of the methyl sulfonates was shown to react at nearly identical rate. In great contrast, oligomers that are long enough to fold, and hence capable of binding the methyl sulfonate, experience rate enhancements of 18-1600-fold relative to that of the small-molecule analogue, depending on the type of alkyl chain attached to the guest. Three different oligomer lengths were studied, with the longest oligomers exhibiting the fastest rate and greatest substrate specificity. Even large, bulky guests show slightly enhanced methylation rates compared to that with the reference DMAP, which suggests a dynamic nature to the oligomer's binding cavity. Several mechanistic models to describe this behavior are discussed.
