A Two-State Reactivity Model Explains Unusual Kinetic Isotope Effect Patterns in C-H Bond Cleavage by Nonheme Oxoiron(IV)Complexes

摘要

The surging field of nonheme iron chemistry has led to the identification of a variety of iron(IV)oxo intermediates,which perform oxidative processes such as hydrogen-atom abstraction(H-abstraction)and oxo-transfer reactions with a variety of molecules.The advent of both enzymatic and synthetic examples has revealed in turn some puzzles of fundamental importance in mechanistic bioinorganic chemistry.
