Ligand redistribution reactions of some organometallic rhodium and iridium complexes

Ligand redistribution reactions of some organometallic rhodium and iridium complexes have been investigated and their possible reaction pathways have been discussed.

Ready formation of stable cationic Rh(I) complexes of MeCN, formamide, urea and related species via replacement of the triflate in trans-(Ph3P)2Rh(CO)(OTf)

The weakly-coordinated trifluoromethanesulfonate (triflate) in trans-(Ph3P)2Rh(CO)(OTf) (OTfOSO2CF3) can be readily replaced by ligand L to form stable ionic complexes [trans-(Ph3P)2RhL(CO)

Relative affinities of carbonylbis(triphenylphosphine)rhodium(I) and related cations for anionic ligands in CH2Cl2

Infrared spectroscopy has been used to determine the relative anion affinities in CH2Cl2 of Rh(PPh3)2(CO)+ and Rh(AsPh3)2(CO)+ via measurement of equilibrium constants for the metatheses RhL2(CO)Y + PPN+Z- = RhL2(CO)Z + PPN+Y-. Observed for L = PPh3 was the anion affinity trend NCO- ? O2CMe- ～ O2CPh- ? F- ～ NCS- > Cl- > Br- > I- ? ONO2- ～ O2CCF3- ? OTf- ～ OClO3-. A smaller series for L = AsPh3 displayed a similar trend, but with positions of NCS- and Cl- reversed. For most anion pairs studied, the equilibrium lies so far to the left or right that only limits could be calculated, given the inherent experimental limitations. For L = PPh3, the equilibrium constant for replacement of the least preferred anion by the most can be inferred as >1019. Rh(PCy3)2(CO)Cl and Rh(PCy3)2(CO)Z (Z = NCS, NCSe, O2CMe; but not F, O2CPh, and NCO) interact strongly in solution and thus limit study of that series.
