Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flow system, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3CO2K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3] sources.
追根溯源:芳基/杂芳基碘化物的三氟甲基化已被证明使用流动系统,从而实现快速反应。使用 CF 3 CO 2 K 作为三氟甲基源,以良好到极好的收率制备了广谱的三氟甲基化化合物。该方法具有反应时间短的优点并使用方便的[CF 3 ]源。
