我们已经描述了在室温下CsF催化的杂芳族醛的三氟甲基化以非常好的收率得到含三氟甲基的醇。使用在甲苯中的催化量的CsF(0.2当量),在室温下以良好的产率获得了三氟甲基化的产物。基板范围已经以大量基板为例。作为一种应用,碘醚化/环化也已被证明可以非常好地由邻炔基三氟甲醇合成三氟甲基吡喃并[4,3- b ]喹啉。

heteroaromatic aldehydes at room temperature to afford trifluoromethyl group containing alcohols in very good yields. Using catalytic amount of CsF (0.2 eq.) in toluene, trifluoromethylated products were achieved in good yields at rt. The substrate scope has been exemplified by a large number of substrates. As an application, iodo etherification/cyclization has also been demonstrated for the synthesis of trifluoromethyl
