Tunneling in C-H Oxidation Reactions by an Oxoiron(IV) Porphyrin Radical Cation: Direct Measurements of Very Large H/D Kinetic Isotope Effects

[Image: see text] Rate constants for oxidations of benzyl alcohol-d(0) and -d(7) by oxoiron(IV) tetramesitylporphyrin radical cation perchlorate in acetonitrile were measured in single-turnover kinetic studies. The kinetic isotope effect (k(H)/k(D)) increased from 28 at 23 °C to 360 at −30 °C due to...
