An unprecedented reactivity of CF3-TMS has been revealed, which exploits the basic character of the generated [CF3–] capable of delivering dichloromethide from dichloromethane with subsequent transfer to nitrones under smooth conditions. The proton-abstraction pathway was demonstrated through isotopic labeling experiments in CD2Cl2. The same reaction was achieved in acetonitrile with the introduction
CF的前所未有的反应3 -TMS已经揭示,其利用的基本特征所生成的[CF 3 - ]能够与后续的光滑的条件下转移到硝酮从二氯甲烷递送dichloromethide的。通过CD 2 Cl 2中的同位素标记实验证明了质子吸收途径。在氰基上引入氰基甲基后,在乙腈中完成了相同的反应。
