Abstract
The compound trans-4-(4'-methylphenyl)cyclohexylmethanol was synthesized in yield of 43.4% from 1-bromo-4-methylbenzne and 3,3-dimebhyl-1,5-dioxaspiroundecan-9-one by Grignard reaction,dehydration reaction,catalytic hydrogenation,Wittig reaction,hydrolization,isomerization and reduction with potassium borohydrid.The structure was characterized by1H NMR,13C NMR and MS.The synthesized substance could be used as an important intermediate for multi-ring system liquid crystal compounds cintaining vinylidene linkage.
