Much of what is known about phosphinimide and phosphinimine complexes of the transition and main-group metals arises from the numerous structural studies described by Dehnicke and co-workers. While some studies of the chemistry of the complexes of these ligands have appeared, in general, such systems are unexplored. Recently, we have demonstrated that early metal-phosphinimide species can act as highly active olefin polymerization catalysts. Although Reetz et al. have begun to employ chiral bidentate bisphosphinimines in asymmetric synthesis, in general, heteroatomic bidentate ligands containing phosphinimine and phosphazides donors have received little attention. In efforts to develop the new potentially bidentate ligand systems for use with late transition metals, we have investigated the synthesis of phosphinimine and phosphazide derivatives of trialkylphosphines that incorporate thioether units. The structures of Ni and Fe complexes of these ligands are presented, and the implications for the development of new bidentate phosphinimine-based ligand systems are considered.
