| Abstract: | A series of SFM thane-type liquid crystals were synthesized from 4 -chloromethyl-4′ -alkyl-bicyclohexyl and 3, 4, 5-Trifluorobenzonitrile as the raw materials. They were synthesized to intermediate ketone following Grignard reaction pathway. And then the ketone was reduced in the fashion of Wolff-Kishner-Huang-Minlon reduction to gain the final product. The total yield is higher than 60%. |
