The neutral bis-cyclopentadienyl metal compounds of iron, cobalt, and nickel were prepared and studied as possible sources of catalytically active iron, cobalt, and nickel. Nickelocene and cobaltocene are reduced to the free metal and cyclopentane in cyclohexane solution with hydrogen in the absence of a catalyst using hydrogen at 1000 psi. The reduction of nickelocene takes place at 60°, and the reduction o! cobaltocene occurs at 160-170°. Induction periods were observed. The hydrogen reduction of ferrocene was not achieved. The hydrogenation reactions of benzene , cyclohexene , acetone , ethyl laurate , nitrobenzene , and nitroethane were studied with nickelocene and cobaltocene added as sources of nickel and cobalt, respectively.
