摘要/Abstract

含氟乙基化产物在生物医药和材料领域有着广泛的应用, 合成含氟乙基的化合物有着重要意义. 目前对三氟乙基化合物的合成有了相关报道, 但是对于如何合成二氟乙基化产物却鲜有报道. 通过氯二氟高价碘试剂和酰胺进行反应, 选择性生成氮-氯二氟乙基化和氧-氯二氟乙基化产物, 该反应的选择性通过溶剂选择即可调控, 反应高效便捷实用.
关键词: 氯二氟乙基高价碘, 氟乙基化, 二氟乙基化, 三氟乙基化
Fluoroethylation products have a wide range of applications in the fields of biomedicine and materials, and the synthesis of fluorine-containing ethyl compounds is very important. At present, there are related reports on the synthesis of trifluoroethyl compounds, but there are few reports on how to synthesize difluoroethylated products. In this paper, through the reaction of chlorodifluoro iodine reagent and amide, N-chlorodifluoroethylation and O-chlorodifluoroethylation products were selectively generated. The selectivity of the reaction can be controlled by the choice of solvent, and the reaction is efficient, convenient and practical.
Key words: chlorodifluoroethyl hypervalent iodine reagent, fluoroethylation, difluoroethylation, trifluoroethylation
