A Mechanistic Switch in C-H Bond Activation by Elusive FeV(O)(TAML)Reaction Intermediate:A Theoretical Study
文献摘要:
The divergent behavior of C-H bond oxidations of aliphatic sub-strates compared to those of aro-matic substrates shown in Gupta's experiment was mechanistically studied herein by means of den-sity functional theory calculations.Our calculations reveal that such difference is caused by different reaction mechanisms between two kinds of substrates(the aliphatic cyclohexane,2,3-dimethylbutane and the aromatic toluene,ethylbenzene and cumene).For the aliphatic substrates,C-H oxidation by the oxidant FeV(O)(TAML)is a hydrogen atom transfer process;whereas for the aromatic substrates,C-H oxidation is a proton-coupled electron transfer(PCET)process with a proton transfer character on the transition state,that is,a proton-coupled electron transfer process holding a proton transfer-like transition state(PCET(PT)).This difference is caused by the strongπ-π interactions between the tetra-anionic TAML ring and the phenyl ring of the aromatic substrates,which has a"pull"effect to make the electron transfer from substrates to the Fe=O moiety inefficient.
