• Radical Addition of 2,2,2-Trifluoroethyl Iodide to Terminal Alkenes

  DOI：10.1055/s-1992-26124

  日期：——

  2,2,2-Trifluoroethyl iodide adds to terminal alkenes under free radical conditions in good yields if the radical initiator is added in successive portions to the reaction mixture. Reduction of the resulting secondary iodides with sodium borohydride gives the corresponding trifluoroethyI-substituted products in overall yields of 40-60%. The reaction seems to be restricted to vinyl double bonds

  在自由基条件下，2,2,2-三氟乙基碘与末端烯烃加成，如果将自由基引发剂分批加入反应混合物，可以获得良好的产率。通过使用硼氢化钠还原生成的二级碘化物，总体产率在40-60%的范围内得到了相应的三氟乙基取代产物。该反应似乎仅限于乙烯双键上。
