The reaction of chloromethyl thiocyanate with 1-methylimidazole affords the imidazolium salt, 1-thiocyanomethyl-3methylimidazolium chloride, [C 1 SCNmim]Cl (1a). Exchange of the chloride anion in 1a by [PF 6 ] -, [BF 4 ] -, [Tf 2 N] -or [AuCl 4 ] -affords salts 1b, 1c, 1d and 1e, respectively. Salts

## Abstract The two known Meβ and allylβsubstituted 1__H__βimidazolβ3βium bromides **1** and **2**, respectively, were converted to the corresponding BF$\rm{\_{4}^{-}}$ and BPh$\rm{\_{4}^{-}}$ salts **3**β**6** (__Schemeβ 1__). Compounds **3** and **4** were liquids at ambient temperature. Reaction
## Abstract Ionic liquids were synthesised that consisted of two methylimidazolium rings joined by a spacer 1β12 carbon atoms in length. The bis(triflic)imides with spacer β€C~4~ were solids; the others were liquid at room temperature. The polarity of the dication liquids and their performance in th
