Ligand Synthesis for Catalysis
In the search for novel reactivity the synthesis of new
ligands can be fundamental. An essential focus is therefore on the
development of new ligand systems to improve known catalytic systems or
develop new systems.

Ortho-substitution of salicylaldehydes
with either anthracene or triptycene leads to two different classes of
salicylaldimine for bidentate or tridentate ligands in the chromium
catalysed polymerisation of ethylene. These systems are amongst the
most active known for homogeneous chromium based systems. |

Development of C2 symmetric complexes for the isotactic
polymerisation of propylene remains a significant challenge with few
significant advances in the recent past. It is believed that
development of new ligand systems which generate C2 symmetric
complexes is essential and is problematic. We will shortly publish a
simple synthesis of new pyrrole based ligands, eg.
bis(napthylpyrryl)methanes, which may give C2 complexes on
coordination. |

A new general and selective functionalisation
of coordinated phosphines has allowed for the first time the synthesis of
a range of trisubstituted triphosphacyclododecanes. The method has
been simplified to allow the synthesis of a range of primary phosphines.
This work is currently being completed for publication. |

analogues of DIPAMP type ligands for olefin polymerisation
catalysts. (To be published after publication of related patents). |
