芳烃三氟甲基化合物价廉易得, 通过对其C(sp3)—F键进行选择性切断是合成含偕二氟基团医药中间体的重要途径. 然而, 该转化中面临着巨大挑战, 如C(sp3)—F键难以活化, 以及如何实现选择性脱单氟键等问题. 近年来该领域发展迅速, 取得了一系列重要的研究成果. 如通过对三氟甲基的转化, 开发出了构建偕二氟烷基基团的简洁而高效的方法,其中涉及二氟烷基自由基或二氟甲基碳阳离子中间体. 根据ArCF3选择性切断单C(sp3)—F键的策略进行分类, 对该领域最新研究进展进行了概述.

Trifluoromethylarene compounds are readily available, and the highly selective cleavage of one C(sp3)—F bond in trifluoromethyl group is an important strategy to access pharmaceutical molecules containing the gem-difluoro groups. However, there are still some challenges in this field, such as the difficulty in activating the C(sp3)—F bond and the highly selective cleavage of the single C(sp3)—F bond. In recent years, efficient methods for the construction of gem-difluoro groups have been developed through the transformation of trifluoromethyl group, in which difluoroalkyl radicals or difluoromethyl carbocation intermediates are alway involved. The recent research progress in this field is summarized based on the cleavage strategies of trifluoromethyl group.

Key words: selective cleavage of C—F bond, trifluoromethylarenes, difluoroalkyl radical
