Studies on ruthenium(II) Schiff base complexes as catalysts for transfer hydrogenation reactions

摘要

The reactions of [RuHCl(CO)(B)(EPh3)2] (B = EPh3 or Py; E = P or As) and Schiff bases in 1:1 molar ratio led to the formation of [RuCl(CO)(EPh3)(B)(L)] (E = P or As; B = PPh3, AsPh3 or Py; L = Schiff base ligand). The new complexes have been characterized by analytical and spectroscopic (IR, electronic and 1H NMR) data. They have been assigned an octahedral structure. The new complexes were found to catalyse the transfer hydrogenation of ketones.
