摘要：

The reaction of 1-n-butyl-3-methylimidazolium chloride (BMIC) with sodium tetrafluoroborate or sodium hexafluorophosphate produced the room temperature-, air- and water-stable molten salts (BMI(+))(BF4-) (1) and (BMI(+))(PF6-) (2), respectively, in almost quantitative yield. The rhodium complexes RhCl(PPh(3))(3) and [Rh(cod)(2)][BF4] are completely soluble in these ionic liquids and they are able to catalyse the hydrogenation of cyclohexene at 10 atm and 25 degrees C in a typical two-phase catalysis with turnovers up to 6000.
