Synthesis, Reactions and Properties of Iron, Cobalt and Nickel Complexes Containing some [P,S]-chelating Ligands and Trimethylphosphine

The work submitted here is concerned with the synthesis and characterization of new [P,S]-chelate complexes of the iron, cobalt and nickel, supported by trimethylphosphine ligands and with an investigation of chemical responses of these systems. Among the new compounds of these metals are stable hydrido and methyl metal compounds in low and high oxidation states which are of particular interest as models for homogeneous catalysis.
