Özet
A series of novel cationic mononuclear rhodium( I) complexes with the P-N-P ligands have been prepared starting from the complex [Rh(cod)(2)]BF4. The structural elucidation of the complexes was carried out by elemental analyses, IR and multinuclear NMR spectroscopic data. Furthermore, the complexes were applied to the transfer hydrogenation of ketones in the presence of 2-propanol as the hydrogen source. Catalytic studies showed that all complexes are excellent catalytic precursors for the transfer hydrogenation of aryl alkyl ketones in 0.1 M iso-PrOH solution. Especially, [Rh((Ph2P)(2)N-C6H4-4-CH(CH3)(2))(cod)]BF4 acts as an excellent catalyst giving the corresponding alcohols in excellent conversion up to 99% (TOF <= 1980 h (1)). (C) 2012 Elsevier B.V.
