α-Bromo- and α-chloroketones may be synthesized in a regiospecific manner in high yields by treatment of an enol borinate with N-bromo- or N-chlorosuccinimide. This method preassembles the carbon skeleton of the ketone, and thereby avoids the problems (isomer formation, polyhalogenation) inherent in other methods. α-Haloesters are also easily synthesized by this procedure.
通过用 N-溴-或 N-氯代琥珀酰亚胺处理烯醇硼酸酯,可以以区域特异性方式以高产率合成 α-溴-和 α-氯酮。这种方法预先组装了酮的碳骨架,从而避免了其他方法固有的问题(异构体形成、多卤化)。α-卤代酯也很容易通过这个程序合成。
