Abstract
The reaction between [RhC5H4CO2(CH)2OH(NBD)] (1) and 1,1’-carbonyldiimidazole (CDI) leads to the new CO2-imidazole functionalized alkoxycarbonylcyclopentadienyl complex [RhC5H4CO2(CH2)2O2C-Im(NBD)] (2) (Im = imidazole). The latter was treated with the five generations of poly(propylenimine) dendrimers DAB-Am-(NH2)n n = 4, 8, 16, 32, 64 (DAB = diaminobutane) to accomplish the synthesis of the new organometallic dendritic macromolecules DAB-dendr-[NH(O)COCH2CH2OC(O)C5H4Rh(NBD)]n n = 4, 8, 16, 32, 64 (4, 5, 6, 7, 8) based on flexible poly(propylenimine) dendrimer cores, built up to the fifth generation. Spectroscopic characterization of all the new compounds will be presented and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
