Abstract
The rate of oxidatively induced homolytic scission of the C(sp(3))-H b onds in the iron phenylcyclohexadienyl complexes Fe(eta(5)-6-PhC(6)H(6 ))(eta(5)-C5H5) (1) depends on the spatial orientation of the Ph subst itutent. In the case of the (1(endo)(+.)) radical cation this process, resulting in the cationic biphenyl complex [Fe(eta(6)-C6H5C6H5)(eta(5 )-C5H5)] (2(+)), is fast and proceeds for several minutes. in the case of the more stable radical cation (1(exo)(+.)) the formation of 2(+) is slow and takes tens minutes to complete.
