【 摘 要 】

Twelve new hexacoordinated ruthenium(II) complexes with organic amides, [RuH(CO)(PPh3)2(L2 )], have been synthesized by treating the precursor, [RuH2(CO)(PPh3)3], with twelve different amide proligands separately. These complexes were characterized by elemental analysis and by UV-vis, IR, ¹H, 13C and 31P NMR spectroscopies. Molecular formulae and octahedral structures have been tentatively proposed for the products. These complexes were found to be efficient in the catalytic reduction of NO2-containing drugs such as chloramphenicol and metronidazole to their amino derivatives. The percent yields of the reduction products were determined spectrophotometrically.
