Abstract

The immobilization of transition metal complexes by bifunctional phosphines containing ethoxysilane groups is of widespread interest. Especially desirable are chelating phosphines, since they can reduce leaching of the metalcomplexes. Easy syntheses of the bifunctional chelating ethoxysilane phosphines Ph2PCH2CH[OSi(OEt)(3)]CH2PPh2, and Ph2P(CH2)(x)P- Ph(CH2)(y)Si(OEt)(3) (x = 2, 3: y = 2, 3), and the nickel derivative (CO)(2)Ni[Ph2P(CH2)(2)PPh(CH2)(2)Si(OEt)(3)] are reported. The ethoxysilane groups present convenient handles for immobilization on oxidic supports.
