In the course of our studies concerning the development of new ester-functionalized Cp ligands we have developed the synthesis of the novel Rh(I) complexes [Rh(L,L)(C5H4CO2(CHR)2OH)] (L,L = 2 CO o 2,5-norbornadiene) (R = H, Me, Ph) that showed catalytic activity in the homogeneous hydroformilation. With the aim of obtaining new dendritic catalysts the complex [Rh(NBD)(C5H4CO2(CH2)2OH] (1) has been anchored on the five generation poly(propyleneimine) dendrimers DAB-Am-(NH2)x (X = 4,8,16,32,64). The synthesis of the new, completely functionalized, organometallic dendritic macromolecules DAB-dendr-[NH(O)COCH2CH2OC(O)C5H4Rh(NBD)]X (X = 4,8,16,32,64) containing peripheral alkoxycarbonylcyclopentadienyl complexes of rhodium(I) will be presented. The application of the same synthetic route toward the immobilization on aminomethylpolystyrene resin will be also presented and discussed.

Abstract
In the course of our studies concerning the development of new ester-functionalized Cp ligands we have developed the synthesis of the novel Rh(I) complexes [Rh(L,L)(C5H4CO2(CHR)2OH)] (L,L = 2 CO o 2,5-norbornadiene) (R = H, Me, Ph) that showed catalytic activity in the homogeneous hydroformilation. With the aim of obtaining new dendritic catalysts the complex [Rh(NBD)(C5H4CO2(CH2)2OH] (1) has been anchored on the five generation poly(propyleneimine) dendrimers DAB-Am-(NH2)x (X = 4,8,16,32,64). The synthesis of the new, completely functionalized, organometallic dendritic macromolecules DAB-dendr-[NH(O)COCH2CH2OC(O)C5H4Rh(NBD)]X (X = 4,8,16,32,64) containing peripheral alkoxycarbonylcyclopentadienyl complexes of rhodium(I) will be presented. The application of the same synthetic route toward the immobilization on aminomethylpolystyrene resin will be also presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
