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.
