By the reaction of olefins with equimolar mixtures of SbCl5 and Br2 or LiBr, and of SbCl3 and Br2, in carbon tetrachloride, various bromochloroalkanes were obtained in good yields. The mixtures of certain metal chlorides of the Lewis acid type (e.g., FeCl3, SnCl4, and TiCl4) and Br2 could also be used as chlorobrominating agents, but these mixtures were found to be inferior to the SbCl5–Br2 mixture
通过烯烃与 SbCl5 和 Br2 或 LiBr 以及 SbCl3 和 Br2 的等摩尔混合物在四氯化碳中的反应,可以以良好的收率获得各种溴氯代烷烃。某些路易斯酸类型的金属氯化物(例如 FeCl3、SnCl4 和 TiCl4)和 Br2 的混合物也可用作氯溴化剂,但发现这些混合物在产品选择性方面不如 SbCl5-Br2 混合物。
