A convenient and efficient method for the synthesis of (Z)-2,4-dihalobutenes, a useful building block in organic synthesis, was reported in good yield by the reaction of alkylidenecyclopropanes and CuX2 (or CuI/I2).
据报道,通过亚烷基
环丙烷与 CuX2(或 CuI/I2)的反应,一种方便有效的方法可以合成 (Z)-2,4-二卤
丁烯,它是有机合成中一种有用的构建基块,而且收率很高。
