Synthesis, Characterization, and Catalytic Application of Palladium Complexes Containing Indolyl-NNN-Type Ligands.

In this study, a series of -heterocyclic indolyl ligand precursors 2-Py-Py-IndH, 2-Py-Pz-IndH, 2-Py-7-Py-IndH, 2-Py-7-Pz-IndH, and 2-Ox-7-Py-IndH (LH-LH) were prepared. The treatment of ligand precursors with 1 equivalent of palladium acetate affords palladium complexes -. All ligand precursors and palladium complexes were characterized by NMR spectroscopy and elemental analysis.
