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.
