Abstract

Emichetali ciclici perfluorurati di formula: (FORMULA I) dove n=1-6, m=2-3, e loro corrispondenti perfluorodichetoni.Questi ultimi sono preparati tramite reazione di perfluoroalchilazione di fluoruri diacilici con perfluoroalchil trialchilsilani. I perfluorodichetoni possono poi essere fatti reagire con H2O per l'ottenimento di detti emichetali ciclici.
