Synthesis and Characterization of Some New Platinum-Imine-Olefin Complexes

Abstract

¹ Hand ¹³C chemical shifts are reported for new type of Schiff bases and amine analogus and their complexes with platinum(II)-olefin compound to form complexes of the type trans-[PtCl₂(η²-C₂H₄)(imine)], trans-[PtCl₂(η²-C₂H₄)](amine)}. (The Schiff base ligand being derived from salicylaldehyde and appropriate primary amine, the amine ligand obtained by the reduction of the appropriate imine). The ¹H and ¹³C spectra provide that only one single rotamer exist in Schiff base ligand solution and when the imine complexes left in solution for several hours, E-Z isomerization occurs.
