Synthesis of ruthenium(II) complexes derived from reduced imine ligands: As catalysts for transfer hydrogenation of ketones

Abstract

N-[2-(benzylamino)phenyl]benzenesulfonamide derivatives (1-6) were successfully synthesized by the reaction of imine ligands derived from various N-(2-aminophenyl)benzenesulfonamides and NaBH 4 . Then, a series of N-coordinate Ru(II) arene complexes 7-12 were prepared from the reaction of [RuCl 2 (p-cymene)] 2 with 1-6. The synthesized compounds were characterized by different methods such as NMR, FT-IR, and elemental analysis. 7-12 were used as catalysts for the transfer hydrogenation (TH) of ketones. At the same time, the effect of various bases such as NaOH, KOH, KOBu t and Et 3 N as organic base were investigated in TH of ketones by 2-propanol as the hydrogen source. 7-12 showed good catalytic activity and so the effects of the different groups were also examined.

Synthesis and Characterization of Half‐Sandwich Ruthenium Complexes Containing Aromatic Sulfonamides Bearing Pyr­id­inyl Rings: Catalysts for Transfer Hydrogenation of Acetophenone Derivatives

“…Sulfonamides containing 8‐aminoquinoline have rarely been studied by the scientific community, and mostly only in relation to their luminescent properties 12–16. Also, catalysis and the molecular structural properties of sulfonamides have recently been studied in detail by our research team 17a–17d…”

Synthesis, characterization and application of Ru(II) complexes containing pyridil ligands for dye-sensitized solar cells

“…Especially, Ru(II) complexes have been used for many applications such as catalysis, medicinal chemistry, photovoltaics, etc. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. The success of these complexes depends on ligand characteristics (electron donation and steric hindrance) [21][22][23][24][25][26].…”
