Ionic liquid solvents N-hexylpyridinium bistrifylimide ([C(6)pyr][Tf2N]] and 1-butyl-3-methylimidazolium hexafluorophosphate ([C(4)mim][PF6]) promoted the displacement of anionic ligands by pyridine derivatives in trans-(Ph3P)(2)Rh(CO)NO3 to a much greater extent than did dichloromethane. Thus, addition of a slight excess of 2-fluoropyridine to trans-(Ph3P)(2)Rh(CO)NO3 in [C(4)mim][PF6] gave a 29:71 product mixture of trans-(Ph3P)(2)Rh(CO)NO3:[trans-(Ph3P)(2)Rh(CO)(2-fluoropyridine)][NO3], while the ratio was 91:9 in dichloromethane.
