2. The molecule below is currently sold as a pre-catalyst for Buchwald-Hartwig coupling reactions. Cy₂P MeHN-Pd-OMS a. What is the oxidation state of the Pd? b. Write a 2-step mechanism to convert the pre-catalyst above to the active Pd catalyst upon addition of base. Make sure to include all products of the reaction. C. Use the angular overlap table to construct a sigma-only d-orbital splitting diagram for a 1- coordinate Pd-PRз complex.
