  Synthesis, structure, immobilization and solid-state NMR of new dppp- and tripod-type chelate linkers

  摘要：

  Chelating phosphines incorporating ethoxysilane functions for immobilizations have been synthesized and fully characterized. (EtO)si(CH2PPh2)(3), (EtO)(2)Si(CH2PPh2)(2), and Si(CH2PPh2)(4) could be prepared in high yields from cheap starting materials. The ethoxysilanes, as well as a Pd complex thereof have been characterized by X-ray structures, and immobilized on silica. The success of the immobilization was proved by P-31 solid-state NMR of the dry materials and of the suspensions. Two representative chelate metal complexes, (EtO)(2)Si(CH2PPh2)(2)PdCl2 and (EtO)Si(CH2PPh2)(3)W(CO)(3) have been synthesized, characterized and immobilized. (c) 2005 Elsevier B.V.
