Nitrosation of α, α'-dianions produced from ketones using a couple of bases was carried out with tert-butyl nitrite(tert-BuONO) in ether, and then two regioisomers of oximes(but not acetone)were obtained simultaneously. The ratio of these regioisomers was remarkably reversed by the addition of hexamethylphosphoric triamide(HMPA).
在乙醚中使用亚硝酸叔丁酯(tert-BuONO)对由酮类生成的α, α'-二元离子进行了亚硝酸化反应,然后同时得到了肟的两种异构体(但不是丙酮)。加入六甲基磷酸三酰胺(HMPA)后,这两种肟的比例发生了显著逆转。
