- A process for preparing β - cyano compound styrene-isobutene method (by machine translation)
-
The invention discloses a on the isobutene β - cyano styrene synthetic method of the compound. The method utilizes a cinnamic acid compounds and azo azobisisobutyronitrile as reaction raw material, the ferric iron catalytic, in the acetonitrile solution in heating by the reaction to the isobutene escapes suosuo the coupling β - cyano styrenic compound. The preparation method of the raw material, cheap and easily obtained catalyst, mild reaction system, the operation is simple, non-ligand, alkali, such as participation of the oxidizing agent. At the same time, use of non-toxic azo azobisisobutyronitrile as a cyano source, has outstanding safety, green and environmental protection. (by machine translation)
