摘要
1-(3,4-difluorophenyl)-2-[trans-4′-(trans-4″n-alkyl cyclohexyl)cyclohexyl]ethane type liquid crystal compounds were synthesized from 4-(trans-4′n-alkyl cyclohexyl)cyclohexnone and methoxymethyltriphenyl phosphonium chloride by Wittig reaction,hydrolization,isomerization,Wittig reaction and hydrogenation.The structures were characterized by ~1H NMR,~(13)C NMR and MS.The overall yield was about 30% after purification.
