Abstract
Abstract The novel cationic N -coordinate ruthenium(II)/arene complexes ( 6–10 ) were prepared from the starting complex [RuCl 2 ( p-cymene )] 2 dimer. The structures of the [( p -cymene)RuLCl]Cl (L = N -arenesulfonyl-4,5-dimethyl- o -phenylenediamines) complexes were elucidated by FT-IR, 1 H-NMR, 13 C-NMR, ionic conductivity techniques, and elemental analysis methods. The 6–10 complexes were applied as catalyst in the transfer hydrogenation (TH) of ketones. The catalytic tests showed that all the complexes are moderate catalysis precursors. Especially, {[ N -benzenesulfonyl-4,5-dimethyl- o -phenylenediamine]-( p -cymene)-di-chloro-ruthenium(II)} ( 8 ) and {[ N -4-chlorobenzenesulfonyl-4,5-dimethyl- o -phenylenediamine]-( p -cymene)-di-chloro-ruthenium(II)} ( 9 ) compounds were found to be a good catalysts in comparison to the others giving the corresponding alcohols in a good turnover frequency value of 1534 and 1731 h −1 , respectively.
