德国有机氟化学专家Peer Kirsch （《现代有机氟化学》一书的作者）的评论如下：        The insertion of CF2 during copper-catalysed trifluoromethylation of iodoarenes has been known as a side reaction for decades: the resulting products always contained a few percent of the pentafluoroethyl homologue which was nearly impossible to remove from the product. It is amazing how this undesired reaction has finally turned into something useful.   报道原文：（PDF） 报道链接：https://www.chemistryworld.com/news/simple-way-to-construct-molecules-with-perfluoroalkyl-bridges/4010811.article#/
