Abstract

The free radicals ^.CH₂CH₂OH and ^.CH(CH₃)CH₂OH react with iron(II)protoporphyrin, Fe^IIPP, to form the transient complexes (PP)Fe^III - CHRCH₂OH. The spectra of these complexes are reported. The transient complexes decompose in a first-order process via the reaction (PP)Fe^III - CHRCH₂OH → Fe^IIIPP + OH^- + CH₂=CHR. The specific rates of the latter reactions are 80 and 40 s^-1 for the two systems, respectively. The results are compared with those for analogous processes.
