Salts of low melting points, usually called ionic liquids (ILs), have been studied extensively during the last decade [1 – 3]. These liquid salts may serve as solvents for chemical reactions as well as electrolytes in electrochemical devices. The first extensively studied IL was 1-ethyl-3-methyl-imidazolium tetrachloroaluminate ([EMIm][AlCl4]). However such ionic liquids containing AlCl4− are e...

Cucurbit[6]uril was dissolved through encapsulation of an imidazolium-based ionic liquid guest in a pure water environment and the dissolution ability could be tuned by augmenting the imidazolium structure.

Quaternary ammonium salts (quats) are an economically advantageous class of industrial compounds. They have surface-active properties, possess anti-microbial activity and are known to be bioactive (Boethling & Lynch, 1992; Juergensen et al., 2000). Contrary, reports regarding low melting tetraalkylphosphonium salts were relatively rare in the literature during the last decades (Bradaric et al.,...

Reactions of primary imidazolio-phosphides (“imidazolylidene-phosphinidenes”) with R2SnCl2 yield as main products spectroscopically detectable Lewis pairs which undergo base-induced dehydrochlorination in the presence excess dichlorostannane to afford zwitterionic chloride adducts distannylated imidazolio-phosphines. In contrast, reactions R3SnCl proceed under dismutation furnish mixtures conta...

1-alkyl-3-methyl-imidazolium (Cn-mim) salts are examples of ionic liquids (ILs).[1] In these salts, the cation is a bulky organic molecule: accordingly, due to factors such as the hindered ion packing and low charge density, the melting point is relatively low compared with conventional inorganic salts. As a consequence, it is possible to synthesise ILs which are liquid at room temperature. The...

Zeolite synthesis is a wide area of study with increasing popularity. Several general reviews have already been published, but they did not summarize the study of imidazolium species in zeolite synthesis. Imidazolium derivatives are promising compounds in the search for new zeolites and can be used to help understand the structure-directing role. Nearly 50 different imidazolium cations have alr...
