摘要:
The dppp ligand 4(T-0) being provided with a T-silylfunctionalized (CH2)(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 can be hydrosilylated with HSi(OMe)(3) to give 3(T-0). Finally both chlorine atoms in 3(T-0) are exchanged by PPh2. Treatment of (COD)PdCl2 with 4(T-0) results in the formation of the T-silylfunctionalized palladium complex 5(T-0).
