- W2106201807 abstract "Abstract The cation [(1-5-η-C6H7)Fe(CO)3]+ (I) has been shown to react with a variety of methoxy-benzenes to give novel diene-substituted aromatic species according to eqn. (1) (ArH = 1,3,5-trimethoxy-, 1,2,3-trimethoxy-, 1,2,4-trimethoxy-, 1,3-dimethoxy-, and 1,4-dimethoxybenzene). For each reaction in CH3NO2 solvent, the rate law Rate = [(C6H7)Fe(CO)3]+ + arH → [(Ar·C6H7)Fe(CO)3] + H+ (1) = K2k1[complex][ArH]/(1 + K1[ArH]) is observed. This is interpreted in terms of an electrophilic substitution mechanism involvin rapid pre-equilibrium formation (K1) of a η-complex followed by rate-determining rearrangement (k2 to a Wheland-type σ-complex intermediate. Rapid proton loss then leads to the observed products." @default.
