In the course of our studies concerning the chemistry of new ester-functionalized Cp ligands, we have disclosed a new procedure for the one pot synthesis of a variety of alkoxycarbonylcyclopentadienides Na[CpCO2(CHR)2OH] (1) [R = H, Me, Ph]. These ligands provided a valuable route to novel sandwich and yhalf-sandwich metal complexes. Among these, the rhodium derivatives [Rh[CpCO2(CHR)2OH](L,L)] (2) [R = H, Me, Ph; L,L = 2CO, NBD], have been tested as hydroformylation and hydrogenation catalysts. The presence in the lateral chain of the Cp ligand of an hydroxyl functionality has been exploited to develop a new route for anchoring the rhodium complexes on the surface of suitable dendrimers and polystyrene resins.

Abstract
In the course of our studies concerning the chemistry of new ester-functionalized Cp ligands, we have disclosed a new procedure for the one pot synthesis of a variety of alkoxycarbonylcyclopentadienides Na[CpCO2(CHR)2OH] (1) [R = H, Me, Ph]. These ligands provided a valuable route to novel sandwich and yhalf-sandwich metal complexes. Among these, the rhodium derivatives [Rh[CpCO2(CHR)2OH](L,L)] (2) [R = H, Me, Ph; L,L = 2CO, NBD], have been tested as hydroformylation and hydrogenation catalysts. The presence in the lateral chain of the Cp ligand of an hydroxyl functionality has been exploited to develop a new route for anchoring the rhodium complexes on the surface of suitable dendrimers and polystyrene resins.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
