We have designed and synthesized a new series of liquid crystalline compounds with hybridized three-ring system based on bicyclo [2.2. 2] octane unit together with fluorine substituted phenyl and biphenyl fragments. The key stages of the synthesis are alkylation of substituted benzene in concentrated sulfuric acid by bicyclo [2.2. 2] octanoles and further cross-coupling between 3, 4-difluorophenylboronic acid and the alkylation product. The ...
