    • 2, and 20 mL of hexane was added to precipitate the metal complex. After filtration on Celite, the precipitate was dissolved in MeOH. Removal of volatiles in vacuo left behind a yellow bright solid (m = 182 mg, yield = 85%), which could be used without any further purification. Crystals were obtained from MeOH.

    • Note
    • DIPPAM/Pd complexes are very stable toward air and can be easily purified by chromatography on silica gel.
