Abstract
Abstract Interaction of diisopropyl methylphosphonate with trivalent metal chlorides at 50–200°C leads to the formation of tris-(isopropoxy methylphosphonato) metal complexes. Tetravalent metal chlorides yield under similar conditions bis-(methylphosphonato) complexes. During these reactions isopropyl chloride is evolved, which is partially decomposed to hydrogen chloride and propene by the catalytic action of the complex metal chloride residue. The general insolubility and the magnetic properties of the new complexes are suggestive of polynuclear configurations, involving eight-membered phosphonate bridges and, possibly, four-membered chelate rings. A distorted O h ligand-field symmetry is assigned to the metal ions.
