| Abstract: | Selective reduction of the phenyl ring beared carboxyl group was realized successfully with sodium and amyl alcohol at 140145 . Through cistrans isomerization trans4(4pentylphenyl)cyclohexyl carboxylic acid and trans4 cyclohexyl carboxylic acid were obtained in good yield and their structures were characterized by elemental analysis, IR, 13C NMR and MS measurements. |

| Keywords: | trans cyclohexane carboxylic acid derivative cistrans isomerization selective reduction liquid crystal material synthesis |
