  • New approach to electrochemical iodination of arenes exemplified by the synthesis of 4-iodopyrazoles of different structures
    作者:B. V. Lyalin、V. A. Petrosyan
    DOI:10.1007/s11172-014-0438-5
    日期:2014.2
    The two-stage electrosynthesis of 4-iodosubstituted pyrazole derivatives was performed. At the first stage, KIO3 was obtained at the Ni anode under the undivided galvanostatic conditions of electrolysis of an aqueous alkaline solution of KI (or I2) at the Ni anode. At the second stage, pyrazole and its derivatives were iodinated in the heterophase (H2O-CHCl3 (CCl4)) medium by the KIO3-KI (or KIO3-I2) system in the presence of H2SO4. The yields of iodopyrazoles were 74–92%. The electrochemical iodination of anisole, 2-methylpyrazole, and thiophene was carried out to form 4-iodoanisole (88% yield), 4,5-diiodo-2-methylimidazole (54% yield), and a mixture of 2-iodothiophene (60% yield) and 2,5-diiodothiophene (4% yield).

  • Electrosynthesis of 4-iodopyrazole and its derivatives
    作者:B. V. Lyalin、V. A. Petrosyan、B. I. Ugrak
    DOI:10.1007/s11172-010-0277-y
    日期:2010.8
    Electrosynthesis of 4-iodo-substituted pyrazoles has been accomplished by iodination of the corresponding precursors on a Pt-anode in aqueous solutions of KI under conditions of the diaphragm galvanostatic electrolysis. Efficiency of the process depends on the donor-acceptor properties of substituents and their positions in the pyrazole ring. Thus, iodination of pyrazole, 3,5-dimethylpyrazole, 3-nitropyrazole
    4-取代吡唑的电合成是通过在隔膜恒电流电解条件下在 KI 溶液中的 Pt 阳极上化相应的前体来完成的。该过程的效率取决于取代基的供体-受体性质及其在吡唑环中的位置。因此,吡唑3,5-二甲基吡唑3-硝基吡唑1-甲基吡唑1,3-二甲基吡唑吡唑-3(5)-羧酸或甲酯的化在 57、86、2、产率分别为 5、35、30 和 40%。

    日期:2013.4
    A synthesis of 4-iodo-substituted pyrazoles by iodination of pyrazole and its derivatives in the heterophase (H2O/CHCl3 (CCl4)) medium with the system KI-KIO3 in the presence of H2SO4 additives was accomplished. The yields of 4-iodo-substituted pyrazoles in the iodination of pyrazole, 3,5-dimethylpyrazole, pyrazole-3(5)-carboxylic acid, 1-methylpyrazole-3-carboxylic acid, 1-methylpyrazole-5-carboxylic acid, 3-nitropyrazole, 1-methyl-3-nitropyrazole, 1-methylpyrazole, 1-ethylpyrazole, and 1-isopropylpyrazole were within 80–97%, whereas in the case of 3-nitropyrazole-5-carboxylic acid it was 32%.
