preparation of benzonitrile to cinnamic acid?
Hello candidate,
Here is a detailed preparation process of benzonitrile to cinnamic acid-
1. First of all, the process for the preparation of a cinnamic acid comprises condensing a benzonitrile with an acetic acid ester in the presence of a base.
2. The reaction mixture is then treated, without adding an additional solvent or after adding an additional solvent, with an acid to convert a 3-alkoxy-3-phenylpropionic acid ester in the reaction mixture into a corresponding cinnamic acid ester.
3. This procedure allows cinnamic acid derivatives of high-purity to be obtained in good yield.
