  摘要：

  An efficient preparation of 1-[Br-79]bromo-2-fluoroethylene, [Br-79]BrHC=CHF, was carried out by a three-step procedure: (a) natural 1-bromo-2-fluoroethylene, BrHC=CHF, was iodinated to 1-fluoro-2-iodoethylene, FHC=CHI; (b) 1-fluoro-2-iodoethylene was Br-79(2)-brominated to 1,2-di[Br-79]bromo-1-fluoro-2-iodoethane, [Br-79]BrFCHCH[Br-79]BrI; ad (c) 1,2-di[Br-79]bromo-1-fluoro-2-iodoethane was dehalogenated to 1-[Br-79]bromo-2-fluoroethylene, [Br-79] BrHC=CHF. The yield of isolated product, on a 2-mmol scale, was 62% with respect to B-79(2).
