    • Hfcpp was prepared by slight modification of reported procedure (W. R. Thiel, T. Priermeier, D. A. Fiedler, A. M. Bond, M. R. Mattner, J. Organomet. Chem. 1996, 514, 137, Synthesis of 1-ferrocenyl-3-(2- pyridyl)-1,3-propanedione: A solution of sodium ethoxide (1.09 g, 15.9 mmol, acetylferrocene (2.00g, 8.77 mmol) and picolinic acid ethyl ester (2.89 g, 19.1 mmol) in 30 mL of toluene was refluxed for 2 h under nitrogen atmosphere. The solvent was removed under reduced pressure, and aqueous acetic acid was added to the residue. The resulting aqueous solution was extracted with diethyl ether and dried with sodium sulfate. The solvent was evaporated, and the recrystallization of crude products from methanol yielded a purple crystalline solid of 1-ferrocenyl-3-(2-pyridyl)-1,3-propanedione (Yield 2.35 g, 81, Anal.

    • Synthesis of 1: An acetonitrile solution (30 mL) of Ni(ClO 4)2·6H2O (55 mg, 0.15 mmol) was added to a mixture of Hfcpp (50 mg, 0.15 mmol) and Et3N (15 mg, 0.15 mmol, The resulting red solution was allowed to stand for a week at room temperature to give red plate crystals of 1 (Yield 6.9mg, 13, ESIMS observed m/z 1551.7, M, 2ClO4]2, Anal.
