Square-Planar Diacetatopalladium Complexes with trans-Configured Secondary Amine Ligands that Avoid Orthometalation: Ligand Synthesis, Coordination, Molecular Structure and Catalytic Potential for Suzuki Cross-Coupling Reactions

Chahen, Ludovic ; Therrien, Bruno ; Süss-Fink, Georg

In: European Journal of Inorganic Chemistry, 2007, vol. 32, p. 5045-5051

The trans-configured square-planar palladium complexes [Pd(OAc)2 (LNtBu)2] (1), [Pd(OAc)2 (η2-LN∩NtBu)] (2), [Pd(OAc)2 (LNPh)2] (3), and [Pd(OAc)2 (η2-LN∩NPh)] (4), have been synthesized by treating palladium acetate with the amines...

1,2-Bis-N-[2’-(diphenylphosphanyl)benzoyl]diaminobenzene, a New Chelating Ligand with Versatile Coordination Properties

Burger, Sylvain ; Therrien, Bruno ; Süss-Fink, Georg

In: European Journal of Inorganic Chemistry, 2003, vol. 17, p. 3099 - 3103

1,2-Bis-N-[2’-(diphenylphosphanyl)benzoyl]diaminobenzene (dppbH; 1) was prepared by peptidic coupling and shown to exist, in the solid state, in the form of hydrogen-bonded dimers by single-crystal X-ray structure analysis. As expected, 1 reacts with [MCl2 (cod)] (M = Pd, Pt; cod = cyclooctadiene) to form square-planar complexes. However, in the case of palladium...
