Process for the preparation of halogenated hydrocarbons with at least 3 carbon atoms in the presence of iron and a phosphite
Abstract:
A telomerisation process is described whereby haloalkanes like tetrachloromethane are added to halogenated olefins like 2-chloroprop-1-ene in the presence of an iron catalyst and a phosphite. The reaction products, e.g. 1,1,1,3,3-pentachlorobutane, can be fluorinated.
Abstract(Chinese):

描述了调聚方法，其中在铁催化剂和亚磷酸盐的存在下，将卤代烷如四氯甲烷加入到卤代烯烃如2-氯丙-1-烯中。 反应产物，例如 1,1,1,3,3-五氯丁烷，可以氟化。
