A series of 2,3-dihalo-1,1,1,4,4,4-hexafluorobutanes and 2-halo-1,1,1,4,4,4-hexafluorobut-2-enes were prepared from commercially available hydrofluoroolefins 1,1,1,4,4,4-hexafluorobut-2-enes and their H, F and C chemical shifts measured. Some reactions of synthesized 2-halo-1,1,1,4,4,4-hexafluorobut-2-enes have been investigated. A simple, one-pot procedure for the preparation of a new allene (1,1,4,4,4-pentafluorobuta-1,2-diene) and some of its transformations is presented.
由市售的氢氟烯烃1,1,1,4,4,4 - 六氟 - 2 - 丁烯制备了一系列2,3 - 二卤 - 1,1,1,4,4,4 - 六氟丁烷和2 - 卤 - 1,1,1,4,4,4 - 六氟 - 2 - 丁烯，并测量了它们的H、F和C化学位移。对合成的2 - 卤 - 1,1,1,4,4,4 - 六氟 - 2 - 丁烯的一些反应进行了研究。介绍了一种制备新型丙二烯（1,1,4,4,4 - 五氟 - 1,2 - 丁二烯）的简单一锅法及其一些转化反应。
