| Abstract: | hydroxy-4′-cyano-biphenyl could be synthesized by esterification(to protect hydroxyl), F-C reaction, ammonolysis, hydrolysation and dehydration of 4-hydroxy- Biphenyl. In comparison with the other synthetic routes, the operation was easy to be operated, and the yield was proved(the whole yield was 47.7%). And it was easy for manufacture. |
