Reductive silylation of benzene yields cis/trans-3,6-bis(trimethylsilyl)-1,4-cyclohexadienes (1a/1b), which react with pentacarbonyliron to give tricarbonyliron complexes (2a/2b and 2c), respectively, in good yields.Reaction of 2a with triphenylmethyl tetrafluoroborate leads to isomeric monotrimethylsilylated cationic complexes 7 and 8.Protodesilylation of the isomeric mixture 2a/2b/2c with an excess of trifluoroacetic acid gives tricarbonyliron (10a).
