Novel one-pot synthesis of quaternary ammonium halides: new route to ionic liquids

Applications of functionalized ionic liquids

“…Shreeve and co-workers have contributed greatly in developing ILs based exotic cations. In addition, we saw also increased interests in chiral [66 -70] , sulfonium [71] , quaternary ammonium [72,73] and phosphonium IL [74][75][76] (see Fig. 2).…”

Synthesis, characterization and thermal properties of new aromatic quaternary ammonium bromides: precursors for ionic liquids and complexation studies

“…Compounds 1-9 (Scheme 1) were prepared by using synthetic route described earlier [41] (procedure presented in Scheme 2). All chemicals used in the synthesis were commercially available and used as received from the manufacturer.…”

“…Furthermore, the purification of the product has been found difficult and costly, resulting in low yields. We have recently shown that using a novel one-pot synthesis, R 4 N + X À , R 2 R 0 2 N + X À and R 2 R 0 R 00 N + X À -type of quaternary ammonium halides can be provided selectively, as the product is easily separable with high purity from the reaction mixture [41]. In this paper we present the synthesis, structural characterization and thermal behavior of nine new aromatic quaternary ammonium bromides 1-9.…”

Crystal Structures and Thermal Behavior of Isostructural Bis(dibenzyldimethylammonium) Tetrachlorometallate [M = Mn(II), Co(II), Ni(II) and Zn(II)] Solvates Crystallized from Acetonitrile and/or Methanol Solutions

“…The solutions contained stoichiometric amounts (2:1) of dibenzyldimethylammonium chloride and MCl 2 . Bz 2 Me 2 NCl was synthesized and characterized as described in recent publications [38,39]. Commercial MCl 2 salts were used as received from manufacturers.…”

“…Furthermore, interactions between the cations and anions were in the focus of our research. To examine only the effect of the metal atom on the packing within the crystal structure, the investigations have been carried out varying the first-row transition metal atom and/or the ligands (X = Br and/or Cl) of the anion and using the same counter ion, the dibenzyldimethylammonium cation [38,39], in all experiments. In this paper, we present the crystal structures and thermal behavior of five isomorphic (Bz [40], in which the anions have a distorted tetrahedral geometry.…”
