Abstract
The oxidative addition of the bidentate Schiff base 1,4-(CyN=CH)(2)-2, 5-Cl2C6H2 to tris(dibenzylideneacetone) dipalladium(0) gave the dicycl opalladated complex [(Cl)PdN(Cy>=C(H)C6H2C(H)=N(Cy)Pd(Cl)](n) (1). Tre atment of 1 with LiBr gave the analogous bromo derivative [(Br>PdN(Cy) =C(H>C6H2C(H)=N(Cy)Pd(Br)](n) (2). Reaction of 1 or of 2 with tertiary phosphines in 1:2 or 1:4 molar ratios gave the dinuclear cyclometalla ted [(L)(X)PdN(Cy)=C(H>C(6)H2C(H)=N(Cy)Pd(X) (L)] (3-9), and non-cyclo metallated complexes [(L)(2)(X)PdN(Cy>=C(H)C6H2C(H)=N(Cy)Pd(X)(L)(2)] (10-14) (X=Cl, Br; L=PPh3, PEtPh2, PEt2Ph, PMePh2, as appropriate), re spectively. Treatment of 1 or of 2 with thallium acetylacetonate gave the dinuclear cyclometallated complex COCHCOMe)PdN(Cy)=C(H)C6H2C(H)=N( Cy)Pd(MeCOCHCOMe)] (15).
