Ferrocene Type Diphosphine Ligand

The wide choice of new methods for the synthesis of P-chirogenic phosphines can be appreciated from the above results,. The synthetic description of this chapter ends here and gives place to the great catalytic potential of these ligands.

The six ligands studied in these investigations are shown in Figure 3. For each new ferrocene tetraphosphine prepared, we evaluated the hydrogenation behavior relative to the corresponding diphosphine of the Josiphos or Bophoz type.
