Abstract

The interaction of perfluoropropylbenzene with 1,2,3,4-tetrafluorobenzene or 1,2,4,5-tetrafluorobenzene in an SbF₅ medium at r.t. yields corresponding 1-(tetrafluorophenyl)perfluoro-1-phenylpropanes, which undergo cyclization into perfluoro-9-ethylfluorene or 1,2,3,4,5,7,8,9-octafluoro-9-(pentafluoroethyl)fluorene along with 1,2,3,4-tetrahydro-9H-fluorenes under the reaction conditions. The reaction of perfluoropropylbenzene with 1,2,3,5-tetrafluorobenzene under the same conditions leads to the formation of 1-(2,3,4,6-tetrafluorophenyl)perfluoro-1-phenylpropane, which does not give cyclization products at 50–55 °C.

在SbF5介质中，全氟丙苯与四氟苯反应生成多氟-1-乙基芴

全氟丙苯与1,2,3,4-四氟苯或1,2,4,5-四氟苯在SbF5介质中以rt反应制得相应的1-(四氟苯基)全氟-1-苯基丙烷，在反应条件下环化成全氟-9-乙基芴或1,2,3,4,5,7,8,9-辛氟-9-(五氟乙基)芴以及1,2,3,4-四氢- 9h -芴。在相同条件下，全氟丙苯与1,2,3,5-四氟苯反应生成1-(2,3,4,6-四氟苯基)全氟-1-苯基丙烷，在50-55℃下不生成环化产物。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
