A slurry of the red iron-methylidyne complex, (cis-Cp/sub 2/Fe/sub 2/(CO)/sub 2/(..mu..-CO)(..mu..-CH))/sup +/PF/sub 6//sup -/, Cp=eta-C/sub 5/H/sub 5/), in dichloromethane was stirred under an ethylene atmosphere and warmed from -78/sup 0/C to room temperature, a maroon crystalline product was formed. Evaporation of the solvent in vacuo followed by recrystallization of the product from acetone-ether produced (cis-Cp/sub 2/Fe/sub 2/(CO)/sub 2/(..mu..-CO)(..mu..-CCH/sub 2/-CH/sub 3/))/sup +/PF/sub 6//sup -/. The reaction was monitored by HNMR spectroscopy. The time for 50% conversion was ca 15 min at -20 C. No detectable intermediates or side reactions were noted. Reactions of the complex with propylene, 2-methylpropene, hexenes, and cycloalkenes are discussed.
