本发明的目的是提供一种简单、低成本和工业化的方法,用于生产含有氢和
氟和/或
氯的聚烯烃骨架化合物。生产由式(1)表示的卤代二烯的方法:A1A2C = CA3-CA4 = CA5A6 [其中A1、A2、A5和A6各自独立地表示氢、
氟、
氯、具有1至3个碳原子的(
全氟)烷基或(
全氟)烯基;A3和A4各自独立地表示氢、
氟或
氯;A1到A6中至少有一个是氢;A1到A6中至少有一个是
氟或
氯],包括在零价
金属存在下使相同或不同的由式(2)表示的卤代烯烃(S)A7A8C = CA9X [其中A7和A8各自独立地表示氢、
氟、
氯、具有1至3个碳原子的(
全氟)烷基或(
全氟)烯基;A9各自独立地表示氢、
氟或
氯;X是
溴或
碘]经过偶联反应的步骤。
