| titleOfInvention | Preparation method of fully-substituted propylene cyanide compound |
| abstract | The invention provides a preparation method of a fully-substituted propylene cyanide compound, which comprises the following steps: taking electron-rich alkyne shown in a formula I and an acylcyanide reagent shown in a formula II as raw materials, and catalyzing the acylcyanide reaction by adopting an acid catalyst to prepare the fully-substituted propylene cyanide compound shown in a formula III. The preparation method of the fully-substituted propylene cyanide compound provided by the invention realizes intermolecular acid catalysis cyanidation reaction for the first time, wherein the cyanidation reagent can realize the cyanidation reaction of various electron-rich alkynes, and has the advantages of mild reaction conditions and specific selectivity. |
