4,4′-dialkyl-4-ethynylbicyclohexyl(1) and their coupled derivatives 1,4-bis((4,4′-dialkyl-bicyclohex)-4-yl)butadiyne(2), 1,4-bis(2-((4,4′-dialkyl-bicyclohex)-4-yl )ethynyl)arene(3) are very important liquid crystal compounds with some special characters. In this paper, the preparations of these compounds were developed in which 4,4′-dialkylbicyclohexyl-4-carbonitrile(4) is used as the starting material. Firstly, key intermediate 4-aceto-4,4′-dialkyl-bicyclohexyl (5) was synthesized in good… CONTINUE READING
