Anions of aliphatic nitro compounds R1R2C=NO2− react with nitroso compounds RNO to give nitrones R1R2C=N(O)R. Salts of nitro compounds with metals and Et3N, as well as trimethylsilyl nitronates in the presence of F−, can serve as the sources of the anions. The structure of the nitrones was established by NMR spectroscopy. 1,3-Dipolar cycloaddition of a series of the nitrones obtained to olefins was
脂肪族硝基化合物 R1R2C=NO2− 的阴离子与亚硝基化合物 RNO 反应生成硝酮 R1R2C=N(O)R。硝基化合物与金属和 Et3N 的盐,以及在 F- 存在下的硝基三甲基甲硅烷基酯,可以作为阴离子的来源。硝酮的结构通过核磁共振光谱确定。研究了获得的一系列硝酮与烯烃的 1,3-偶极环加成反应。
