New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. In an article, author is Li, Xiaoyan, once mentioned the application of 530-62-1, Reference of 530-62-1, Name is Di(1H-imidazol-1-yl)methanone, molecular formula is C7H6N4O, molecular weight is 162.1487, category is benzoxazole. Now introduce a scientific discovery about this category.
The umpolung reaction catalyzed by N-heterocyclic carbenes (NHCs) has been widely studied and well recognized, but their role in the nonpolar inversion reaction under oxidative condition has been rarely reported. In this paper, the mechanism of the oxidative nonpolar inversion reaction catalyzed by NHCs to produce benzoxazole is investigated in detail. The reaction occurs through five processes. For oxidation in the second process, two successive tautomerizations followed by oxidation are energetically more favorable than the other two pathways. The rate-determining step is the oxidation by 3,3 ‘-5,5 ‘-tetra-tert-butyl-4,4 ‘-diphenoquinone. Mechanism calculations of the uncatalyzed reaction reveal that the very highly exothermic nature of the initial step is the main reason for the extremely high energy barrier in the following step. With the participation of NHC, this unfavorable transformation can be deftly prevented according to the specific sequence and equivalent of reagent addition, enabling the reaction to occur under mild conditions.
Reference of 530-62-1, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 530-62-1 is helpful to your research.
