Abstract

The reduction of coordinated CO on Cp₂Fe₂(CO)₄ by LiAlH₄ has been investigated with isotopic labeling in an attempt to delineate the chain formation step. Reduction with LiAlD₄ resulted in formation of perdeutero-hydrocarbons. Reduction under an atmosphere of ¹³CO resulted in substantial incorporation of ¹³C into the hydrocarbon products. Reaction of the complexes RFeCp(CO)₂, R CH₃, C₂H₅ and CH₃C(O), with LAD and with LAH under ¹³CO are reported. Reaction of CH₃¹³C(O)FeCp(CO)₂ with LAH is also reported. The results of these reactions suggest that chain extension occurs by a CO insertion reaction, probably by CO insertion into an alkylidenemetal bond.
