The enthalpies of vaporization for the series of pyridinium-based ionic liquids with bis（trifluoromethylsulfonyl）imide anion [CnPy][NTfz] （n = 2, 3, 4, 5, and 6） have been determined with the quartz crystal microbalance technique combined with the Langmuir evaporation. The linear dependence of vaporization enthalpies on the chain length has been revealed. New approach based on volumetric, surface tension, and speed of sound measurements has been developed for estimation of heat capacity differences between gas and liquid phase, which were required for adjustment of measured vaporization enthalpies to the ref- erence temperature 298 K.

Sequential type one pot Nazarov/Michael reaction of pyrrole derivatives has been demonstrated using 5 tool% Fe（C104）3· A120 as catalyst in an ionic liquid as solvent. We succeeded in obtaining 4,5-dihydrocyclopenta[b]pyrrol-6（1H）-one derivative in good yield for five repetitions of the reactions without any addition of the catalyst using an ionic liquid, [bmim][NTf2], as sol- vent system.
