Fluorocyclohexanes—XIII : 1 H,2 H,3 H,4 H-octafluorocyclohexanes

Abstract

From the mixture obtained by the fluorination of benzene over CoF 3 at 150–200° 1 H,2 H: 4 H,5 H/-hexafluorocyclohexene, a 1 H,2 H,3 H,5 H-octafluorocyclohexane and 1 H,2 H,4 H/3 H-octafluorocyclohexane were separated by fractional distillation and preparative scale GLC. The six isomeric 1 H,2 H, 3 H,4 H-octafluorocyclohexanes were synthesized and identified by NMR proton spectra and fluorination to known compounds.
