Mechanistic Studies Of Tert-Butyl Hydroperoxide Decomposition By Iron Salt And Oxidation Of C=C Bond

Fenton reagent has been widely concerned since its discovery,due to its superior oxidizing property.As a reagent with superior oxidizing property,Fenton reagents is used for destroying toxic organic compounds.In the organic chemistry,with the development of transition metal catalysis,the combination of iron and peroxide has been developed into an important catalytic system in organic chemistry,and many efficient and highly selective organic reactions have been achieved.Direct oxidation reaction and Cross-coupling reaction,high efficiency and high selectivity to construct carbon-carbon and carbon-heteroatom bonds,which provide a series of green and high-element economic synthesis methods for organic synthesis.However,although the Fe / peroxide system has achieved many important results in practical application,the detailed mechanism of Fe and peroxide is still not clearly understood.In this process,it is a fact which is the active species hydroxyl radical or high valent state Iron species is still in controversy.Based on the present research situation,this paper attempts to explore the mechanism of iron and peroxide reaction using the C =C oxidation reaction of olefins as a model reaction.In this paper,we summarized the development of Fe / peroxide system and the specific application in organic reaction firstly,then learned about the current research situation of iron and peroxide reaction mechanism.In view of the existing problems and shortcomings in this field,we plan to study the reaction mechanism of iron and tert-Butyl hydroperoxide by DFT calculation and XAFS technique using the C = C oxidation reaction of olefins as a model reaction.The results show that the high valent state Iron-oxo species is involved in the C = C bond cleavage reaction as an active species in the reaction.
