Polar alicyclic rings: synthesis and structure of all cis-1,2,3,4-tetrafluorocyclopentane†
Abstract
The all-cis isomer of 1,2,3,4-tetrafluorocyclopentane is prepared and characterised by NMR and X-ray crystallography and the experimental structure compared with theory. The structure has a similarly high polarity to all-cis tetrafluorocyclohexanes despite the increased conformational flexibility of a cyclopentane.
