Presumed innocent, room-temperature ionic liquids are clean, often reusable, media for carrying out many synthetic, catalytic, separation, and analytical processes. However, they are not simply inert solvents, and a variety of decomposition pathways have been detected. In the structure of 1-n-butyl-3-methylimidazolium hexafluorophosphate shown, reactive bonds are marked with arrows (C grey, N blue, F green, P red).
