The primary radical anions of substrate in the reactions of vicarious nucleophilic substitution of hydrogen in 1‐methyl‐4‐nitropyrazole with 1,1,1‐trimethylhydrazinium iodide and 4‐amino‐1,2,4‐triazole in t‐BuOK–DMSO were observed and identified by EPR monitoring. The probable mechanism of the substrate radical anions formation is discussed. Copyright © 2005 John Wiley & Sons, Ltd.
1-甲基-4-硝基吡唑中氢与1,1,1-三甲基肼碘化物和4-氨基-1,2,4-三唑在t-BuOK-DMSO中的替代亲核取代反应中底物的初级自由基阴离子通过 EPR 监测观察和识别。讨论了底物自由基阴离子形成的可能机制。版权所有 © 2005 John Wiley & Sons, Ltd.
