The use of a methanesulfonic acid/triethylamine trihydrofluoride combination for the direct hydrofluorination of methallyl-containing substrates is reported. Under those metal-free conditions that use readily available, cheap, and easy to handle reagents, a range of methallyl alkenes could be converted to their corresponding tertiary fluoride in up to 78% yield. Finally, a promising result for the
据报道,使用甲磺酸/三乙胺三氟化氢组合物直接对含甲基烯丙基的底物进行氢氟化。在使用容易获得,便宜且易于处理的试剂的无金属条件下,可以将一系列甲基烯丙基烯烃转化为相应的叔氟化物,收率高达78%。最后,报道了该化学物适应连续流动条件的有希望的结果。
