Journal ArticleDOI
The role of hydrogen bonding in controlling the selectivity of Diels–Alder reactions in room-temperature ionic liquids
TL;DR: The reaction of cyclopentadiene with methyl acrylate has been investigated in a range of ionic liquids and the origin of the endo-selectivity for the reactions and associated rate enhancements has been attributed to a hydrogen bond formed between the cation of the ionic liquid and the methyl acid as mentioned in this paper.
Journal ArticleDOI
Manipulating solute nucleophilicity with room temperature ionic liquids.
TL;DR: It was shown that all of the amines are more nucleophilic in the ionic liquids than in the molecular solvents studied in this work, and can be explained in part by the differing hydrogen-bonding properties, as shown by the Kamlet-Taft solvent parameters and the formation of hydrogen bonds between the solvent and the nucleophiles.
Journal ArticleDOI
Nucleophilicity in ionic liquids. 2.(1) Cation effects on halide nucleophilicity in a series of bis(trifluoromethylsulfonyl)imide ionic liquids.
TL;DR: The activation parameters DeltaH(), DeltaS(), and DeltaG() have been estimated for the reaction of chloride in each ionic liquid, and compared to a similar reaction in dichloromethane, where these parameters were found for reaction by both the free ion and the ion pair.
Journal ArticleDOI
Using Kamlet-Taft solvent descriptors to explain the reactivity of anionic nucleophiles in ionic liquids.
TL;DR: The Kamlet-Taft solvent descriptors have been used to analyze the rates of the reactions, which were found to have a strong inverse dependency on the alpha value of the solvent.
Journal ArticleDOI
Precise temperature control in microfluidic devices using Joule heating of ionic liquids
TL;DR: Microfluidic devices for spatially localised heating of microchannel environments were designed, fabricated and tested and enable intra-channel temperature control to within +/-0.2 degrees C.
