Abstract

Zirconium and titanium alkoxide derivatives with phosphanyl substituents were synthesized by reaction of the alkoxides with 2-acrylamido-2-methyl-propane sulfonic acid followed by addition of HPPh2 to the acrylic double bond. Alternatively, the phosphinated sulfonic acid was prepared first and then reacted with the alkoxides. The second route is preferred because of the milder reaction conditions, shorter reaction times and avoidance of byproducts. The bifunctional organic ligand is bonded to the titanium or zirconium atom via the sulfonate group, while the PR2 group is available for further reactions such as the coordination of metal compounds.
