Transition-Metal Derivatives of Phosphinophosphazenes: X-Ray Crystal Structuresof N3P3Cl4PhPPh2, N3P3Cl4PhPPh2.Cr(CO)5, and N3P3Cl4PhPPh2.Ru3(CO)11

摘要

The synthesis of macromolecules that function as carrier species for transitionmetals is of considerable interest because of their potential application as electroactive materials and polymer-supported catalysts. This report describes the synthesis of poly-phosphazenes in which metals are bound to skeletal phosphorus atoms by covalent bonds, via coordination to skeletal nitrogen atoms, or by the use of pendent organic spacer groups. A prudent prerequisite for the synthesis of such high polymeric species is the initial examination of prototype systems at the small molecule level.
