Clean and efficient synthesis of air stable polymer-supported alkoxycarbonylcyclopentadienyl rhodium(I) complexes

Polymer-supported alkoxycarbonylcyclopentadienyl rhodium(I) complexes have been obtained through immobilization of [Rh{C5H4CO2(CH2)2O2C-Im}(NBD)] (2) (Im = imidazole) on an (aminomethyl)polystyrene resin. An alternative approach toward the grafting of [Rh{C5H4CO2(CH2)2OH}(NBD)] (1) on a Wang resin has been also developed. Spectroscopic characterization of all the new functionalized resins with particular accent on ICP-OES measurements is presented and discussed.
