1,3-Dialkylimidazoles salts with different substituents have low melting po
int, often below room temperature. Tetrachloroaluminates of 1,3-dialkylimid
azoles form a new class of solvents. They are not volatile, inflammable and
conduct electric current. However, they require insulation from ambient mo
isture. More recently, moisture-insensitive low temperature ionic liquid we
re synthesized, e.g., tetrafluoroborates and hexafluorophosphates of 1,3-di
alkylimidazoles.
