Synthesis, structure, and quaternization and complexation reactions of κ3SCS pincer palladium complexes having 3,5-pyridinediyl unit

The cyclopalladation of 3,5-bis(diphenylphosphinothioyl) pyridine afforded new kappa S-3,C,S-pincer palladium complexes with a sigma-bond between Pd and 4C of the centered 3,5-pyridinediyl unit. By utilizing the quaternization and complexation ability of the pyridine imine nitrogen (N-py) atom, various new pincer-type complexes, including hetero-binuclear complexes, have been synthesized.
