“…This indicates that the superoxide ion generated in the forward scan is not stable in this ionic liquid as received. Carter et al 19 reported the absence of the reverse peak for the system 1-ethyl-3-methylimidazolium chloride mixed with AlCl 3 and attributed this to inadvertent introduction of protons while conducting their experiments.…”

“…[16][17][18] It is clear that some RTILs can be used to support electrochemistry. Osteryoung et al 19 showed that superoxide ion could be generated by the reduction of dioxygen in imidizalium chloride-aluminum chloride molten salt. However, the resulting superoxide ion was unstable and thus cannot be used as a reagent in subsequent reactions.…”

“…Over the last several years these properties have proven to be important drivers [2][3][4][5][6][7] supporting numerous advances beyond initial investigations of ILs as liquid electrolytes. [8] Current topics of interest include electrochemistry, [9][10][11][12] separation science, [13][14][15][16][17][18] chemical synthesis, [3,5,6,[19][20][21][22][23][24] catalysis, [5,6,21,25,26] and many others. The preparation of ILs, their properties, and application in various fields of chemistry have been recently extensively reviewed.…”

Compartmentalized molecular level design of new energetic materials based on energetic azolate anions allows for the examination of the effects of both cation and anion on the physiochemical properties of ionic liquids. Thirty one novel salts were synthesized by pairing diverse cations (tetraphenylphosphonium, ethyltriphenylphosphonium, N-phenyl pyridinium, 1-butyl-3-methylimidazolium, tetramethyl-, tetraethyl-, and tetrabutylammonium) with azolate anions (5-nitrobenzimidazolate, 5-nitrobenzotriazolate, 3,5-dinitro-1,2,4-triazolate, 2,4-dinitroimidazolate, 4-nitro-1,2,3-triazolate, 4,5-dinitroimidazolate, 4,5-dicyanoimidazolate, 4-nitroimidazolate, and tetrazolate). These salts have been characterized by DSC, TGA, and single crystal X-ray crystallography. The azolates in general are surprisingly stable in the systems explored. Ionic liquids were obtained with all combinations of the 1-butyl-3-methylimidazolium cation and the heterocyclic azolate anions studied, and with several combinations of tetraethyl- or tetrabutylammonium cations and the azolate anions. Favorable structure-property relationships were most often achieved when changing from 4- and 4,5-disubstituted anions to 3,5- and 2,4-disubstituted anions. The most promising anion for use in energetic ionic liquids of those studied here, was 3,5-dinitro-1,2,4-triazolate, based on its contributions to the entire set of target properties.

“…There have been few reports, however, on the dissolution and detection of gases in ionic liquids [16 ± 20]. The one electron reduction of oxygen was first reported by Carter et al [16] in the room temperature imidazolium chloride-aluminium chloride molten salt, although the generated superoxide species proved to be highly unstable in that medium. The electrochemical generation of superoxide has since been studied by cyclic voltammetry in 1-n-butyl-3-methylimidazolium hexafluorophosphate, ( [19].…”

Elucidation of the Electrochemical Oxidation Pathway of Ammonia in Dimethylformamide and the Room Temperature Ionic Liquid, 1‐Ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide

The direct electrochemical oxidation of ammonia has been examined in both the organic solvent dimethylformamide (DMF) and the room temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide [EMIM][N(Tf) 2 ]. The corresponding voltammetric responses have been shown to be similar in each solvent with a broad oxidative wave occurring upon the introduction of ammonia to the solution and the appearance of a new reductive wave following the oxidation. The oxidative reaction process has been examined and a suitable reaction pathway has been deduced, corresponding to the formation of ammonium cations after oxidation of the ammonia. A linear response of limiting current against vol% ammonia was observed in both DMF and [EMIM][N(Tf) 2 ], suggesting potential application for analytical methods.
