Electrochemical methoxylation of substituted 4H-imidazole 1,3-dioxides has been carried out for the first time. Nitroxyl radicals of the 2- and 3-imidazoline series with methoxy groups at the α-carbon atom of the radical site were synthesized. The yields and ratios of the electrochemical methoxylation products are close to those observed in the chemical methoxylation carried out with PbO2 and MnO2
首次进行了取代 4H-咪唑 1,3-二氧化物的电化学甲氧基化反应。合成了在自由基位点的 α-碳原子上具有甲氧基的 2-和 3-咪唑啉系列的硝酰基自由基。电化学甲氧基化产物的产率和比率与在以 PbO2 和 MnO2 作为氧化剂进行的化学甲氧基化反应中观察到的接近。
