SUPPORTED ORGANOMETALLIC COMPLEXES XVI - A T-SILYL FUNCTIONALIZED DPPP PALLADIUM COMPLEX AS A PRECURSOR FOR CATALYSIS IN INTERPHASES

The dppp ligand 4(T-0) being provided with a T-silylfunctionalized (CH 2)(6) spacer in the symmetric position of the C3 bridge is obtained by a simple three step reaction starting with 2-hydroxymethyl-1-hydroxy- 7-octene (1) (Scheme 1). 1 is chlorinated to the dichloride 2 which ca n be hydrosilylated with HSi(OMe)(3) to give 3(T-0). Finally both chlo rine atoms in 3(T-0) are exchanged by PPh2. Treatment of (COD)PdCl2 wi th 4(T-0) results in the formation of the T-silylfunctionalized pallad ium complex 5(T-0).
