  Cationic rhodium(I) complexes containing 4,4′-disubstituted 2,2′-bipyridines: A systematic variation on electron density over the metal centre

  摘要：

  A series of [Rh(COD)(X-2-bipy)]BF4 complexes (COD = 1,5-cyclooctadiene; X-2-bipy = 4,4'-disubstituted 2,2'-bipyridines; X = OCH3, CH3, H, Cl or NO2) has been prepared from [Rh(COD)Cl](2). The complexes for X = OCH3, Cl and NO2 have not been described previously in the literature. All complexes have been characterised by elemental analysis, IR, H-1 NMR and UV-Vis spectrometry. This series of complexes presents a wide variation on electron density over the metal centre with virtually no variation on its steric environment which discloses interesting possibilities for catalytic and electro-catalytic studies. A preliminary evaluation of these complexes on the hydroformylation of camphene and beta-pinene showed that under the rather drastic conditions employed the complexes acted as a precursor for (Rh(CO)(3)H], which accounts for most of the catalytic activity.
