Abstract
Acylation of bis[2-(diphenylphosphino)ethyl]amine provides a flexible synthesis of functionalized chelating diphosphines. This t.uitiott off"rs a route to diphosphine complexes of transition metals having a wide r?n-ge of structures and physical properties and especially to water-soluble complexes. The aqueous solubility of the free ligands and of ttre compleres prepared from them depend on the ligand, on the metal, and on other materials (especially surfactants) present in the solution. We describe typical preparations of ligands and outline the properties of their complexes with certain transition metals.
