of trimethylsilyl-substituted benzene derivatives into nitrosobenzene derivatives is reported. The optimization of the reaction conditions was performed for moderately electron-deficient, electron-rich, and sterically hindered starting materials by varying reaction time, temperature, and equivalents of NOBF4. Also, a stable intermediate of the nitrosation reaction could be characterized by 19F NMR which
报道了三甲基甲硅烷基取代的苯衍生物的亲电子ipso-取代成亚硝基苯衍生物。通过改变反应时间,温度和NOBF 4的当量,对中度电子不足,电子富集和空间受阻的原料进行了反应条件的优化。而且,亚硝化反应的稳定中间体可以通过19 F NMR表征,该19 F NMR可以与亚硝基苯衍生物分配给NO +加成物。该配合物在水后处理中分解并释放出所需的亚硝基苯衍生物。
