  描述：

  4,5-bis(bromomethyl)-1,3-dioxolane-2-thione 在 三氟化溴 作用下， 以 氯仿 为溶剂， 以90%的产率得到2,2-difluoro-4,5-bis(bromomethyl)-1,3-dioxolane

  Constructing the OCF₂O Moiety Using BrF₃

  摘要：

  A general preparation for aromatic and aliphatic, cyclic as well as linear, symmetric and asymmetric difluoromethylenedioxy derivatives is described. The alcohols were reacted with thiophosgene to give thiocarbonates, which in turn were reacted with BrF(3). The fluorination step is complete in seconds with moderate to high yields under mild conditions.
