utilization of decomposition products of PFECAs. We report herein a new series of deoxyfluorination reagents featuring OCF2 functional groups derived from certain PFECAs. Alkyl fluorides were generated from various alcohols in ≤97% yield by these novel reagents. The mechanistic experiment verified in situ generation of carbonic difluoride (COF2).
为了保护环境,继续进行
全氟烷基醚
羧酸(PF
ECAs)替代
全氟烷基物质的研究。但是,关于PF
ECA分解产物的利用了解甚少。我们在此报告了一系列新的脱氧
氟化试剂,其特征在于衍生自某些PF
ECA的OCF 2官能团。这些新型试剂可从各种醇中生成烷基
氟化物,产率≤97%。机理实验证实了原位生成二
氟化碳(COF 2)。
