摘要：

A study was conducted to analyze oxidation of benzene with H 2O2 through benzene oxide with NIH shift. The study used an N-bridged diiron tetra-tert-butylphthalocyanine complex having good solubility in organic solvents for catyalytic reactions. The study also used 1,3,5-[D3]benzene as a probe for the detection of NIH shift. The study found that (FePctBu4)2N showed a high catalytic activity in oxidation of PhH by H2O2 at 20 °C. NIH shift can be defined as a migration of the substituent from the site of hydroxylation to carbon atom and associated with bio-oxidation. The study found that the NIH shift and the formation of benzene oxide are associated with bio-oxidation mediated by cytochrome P-450 and toluene mono-oxygenases.
