3-Trifluoro-1-propenyl)trimethylammonium iodides readily underwent demethylation-allylic substitution followed by N-N exchange reaction at ambient temperature or at 70 °C by the action of various secondary amines or several primary amines to give the corresponding β-fluorinated vinamidinium salts in good yields.
(2,3,3-三氟-1-丙烯基)三甲基碘化碘易于在环境温度或70°C下通过各种仲胺或几种伯胺的作用进行脱甲基化烯丙基取代,然后进行NN交换反应,得到相应的β -氟化的乙烯基ami胺盐,收率高。
