right conditions, bromine trifluoride can be a useful tool for generating new types of reactions and compounds. Thus, tris(methylthio)alkyl derivatives, easily prepared from the corresponding alkyl bromides, were converted to the corresponding RCHBrCF2SMe or RCHBrCF3 compounds. The bromine atom, however, could be easily reduced forming eventually R'CF2SMe or R'CF3. If desired, the bromine atom can serve
在适当的条件下,三氟化溴可能是产生新型反应和化合物的有用工具。因此,容易从相应的烷基溴制备的三(甲硫基)烷基衍生物被转化为相应的RCHBrCF2SMe或RCHBrCF3化合物。但是,溴原子很容易还原,最终形成R'CF2SMe或R'CF3。如果需要,溴原子可以用作构建末端二氟烯烃的入口。
