A general synthetic route to 4-alkyl-4'-cyano-2'3'5'6'-tetrafluorobiphenyls has been developed and used to prepare compounds with unbranched alkyl chains ranging from 4 to 7 carbon atoms. The compounds were characterised by 19F 13C and 1H NMR spectroscopy. One member of the series 4-butyl-4'-cyano-2'3'3'5'6'-tetrafluorobiphenyl was characterised crystallographically at 147 K.
