Abstract
- In this paper, a series of 4-aminophenyl arylsulfonates ( L1 – 3 ) and their Schiff bases ( L4 – 6 ) were synthesized. [Ru( p -cymene)( L1 – 3 )Cl 2 ] ( K1 – 3 ), trans -[Pd(L4-6) 2 ] ( K4 – 6 ), and [Ru( p -cymene)(4-aminophenol)Cl 2 ] ( K7 ) type transition metal complexes have been prepared from the reaction of the appropriate metal salt, L1 – 6 and 4-aminophenol. All compounds characterized with different techniques like C, H, N analysis, NMR, IR and UV–Vis techniques. Solid-state structures of one Ru(II) complex ( K1) and one Pd(II) complex ( K6) have been determined by single-crystal X-ray diffraction. The complexes K1 – 7 have been tested as catalysts for the catalytic oxidation of benzyl alcohol to bezaldehyde in the presence of periodic acid (H 5 IO 6 ). The results show that Ru(II) complexes are more active catalysts than Pd(II) catalysts for this reaction under worked conditions. [ABSTRACT FROM AUTHOR]
