Notes:
The title compound rac-9 and its bis(acetone) complex rac-10 were prepared, and the latter investigated by X-ray structure analysis. rac-10 proves that the coordination of the weak donor acetone, an easily substitutable ligand in PTHs and related compounds, is an essential point for dissolving these coordination polymers, and thus allowing catalysis reactions in such solvents. Furthermore rac-10 shows only a small deviation from the square-planar coordination expected for Pd11. This indicates that the strong deviation from planarity observed in complexes with more sterically demanding, bidentate ligands is caused by steric interactions with the substituents on the PTH, rather than by electronic effects.
