| Abstract: | Cationic pentafluorophenyl palladium(II) complexes of the type Pd(C6F5)L2(APPY)]ClO4 (L = PPh3, PBu3n; L2 = bipy and A acetylmethylenetriphenylphosphorane) have been prepared by addition of APPY to the perchlorato complexes Pd(OClO3)(C6F5)L2]; the APPY ligand is O-coordinated, which is unprecedented in keto-stabilized ylide complexes of palladium.The neutral complex Pd(C6F5)(Cl)(tht)(APPY) has been made by addition of APPY to the binuclear complex Pd2(μ-Cl)2(C6F5)2(tht)2 (tht = tetrahydrothiophene); in which the APPY ligand shows the normal C-coordination. |
