| abstract |
The invention discloses a method for electrochemically synthesizing trans-4-(trans-4'-alkylcyclohexyl)cyclohexylene liquid crystal monomers, comprising: trans-4-(trans-4'-alkylcyclohexyl ) cyclohexyl ketone and vinylsilane carry out electrolytic reaction, then carry out dehydration rearrangement isomerization reaction under acidic catalyst to obtain trans-4-(trans-4'-alkylcyclohexyl)cyclohexylene. The method has short steps, high yield, low cost, environmental friendliness, and is suitable for industrial production. |
