Abstract

The mechanism of halide abstraction from (η⁵-C₅H₅)Fe(CO)₂I with AgBF₄ was investigated by ¹H NMR (CDCl₃ solvent) and infrared (CH₂Cl₂ and CHCl₃ solvents) spectroscopic methods. (η⁵-C₅H₅)Fe(CO)₂I initially forms a silver(I) adduct formulated as (η⁵-C₅H₅)Fe(CO)₂IAg⁺, which decomposes to yield AgI and, in the presence of excess (η⁵-C₅H₅)Fe(CO)₂I, the iodine-bridged species [(η⁵-C₅H₅)Fe(CO)₂] ₂IBF₄. This material then reacts with a second 0.5 equiv of AgBF₄ to yield (η⁵-C₅H₅)Fe(CO)₂BF₄, in which tetrafluoroborate is coordinated.
