perfluoro-1-ethylbenzocycloalkenes transformed further to disubstituted derivatives. In the case of perfluorotetralin, the reaction gave perfluoro-1,4-diethyltetralin. Perfluorobenzocyclobutene gave perfluoro-1,1- and -1,2-diethylbenzocyclobutenes in about equal quantities, and perfluoroindan- practically only perfluoro-1,1-diethylindan. To explain this orientation, the electronic and steric effects are considered
在SbF 5的存在下,全氟四氢化萘,茚满和苯并环丁烯与四氟乙烯的反应导致进一步转化为二取代衍生物的全氟-1-乙基苯并环烯烃的形成。在全氟四氢萘的情况下,反应得到全氟-1,4-二乙基四氢萘。全氟苯并环丁烯产生的全氟-1,1-和-1,2-二乙基苯并环丁烯的数量大致相等,而全氟茚满-实际上仅是全氟-1,1-二乙基二茚。为了解释这种取向,考虑了电子和空间效应,它们可以影响中间碳阳离子的反应性和相对稳定性。
