The oxidative addition of the bidentate Schiff base 1,4‐(CyNCH) 2 ‐2,5‐Cl 2 C 6 H 2 to tris(dibenzylideneacetone) dipalladium(0) gave the dicyclopalladated complex [(Cl)PdN(Cy)C(H)C 6 H 2 C(H)N(Cy)Pd(Cl)] n ( 1 ). Treatment of 1 with LiBr gave the analogous bromo derivative [(Br)PdN(Cy)C(H)C 6 H 2 C(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 cyclometallated [(L)(X)PdN(Cy)C(H)C 6 H 2 C(H)N(Cy)Pd(X)(L)] ( 3–9 ), and non‐cyclometallated complexes [(L) 2 (X)PdN(Cy)C(H)C 6 H 2 C(H)N(Cy)Pd(X)(L) 2 ] ( 10 – 14 ) (X = Cl, Br; L = PPh 3 , PEtPh 2 , PEt 2 Ph, PMePh 2 , as appropriate), respectively, Treatment of 1 or of 2 with thallium acetylacetonate gave the dinuclear cyclometallated complex [(MeCOCHCOMe)PdN(Cy)C(H)C 6 H 2 C(H)N(Cy)Pd(MeCOCHCOMe)] ( 15 ).
