Abstract:	The rate constant for the methyl abstraction reaction of CpFe(CO) 2Me has been measured with the benzyl radical clock as (1.1 ± 0.2) × 105 M-1 s-1 at room temperature. Time-resolved Fourier-transform Infrared (FTIR) absorption spectroscopy pointed towards the formation of the CpFe(CO)2 radical upon benzyl abstraction. The main stable product has been established by a linear scan of the reaction mixture as Cp2Fe2(CO)4 produced by the dimerization of the CpFe(CO)2 radicals. The transition state structure for the abstraction process was also found at UB3LYP/6-311+G* level of theory to contain a planar CH3 group. © 2005 Elsevier B.V. All rights reserved.
