| titleOfInvention | A kind of preparation method of β-hydroxyethyl cinnamaldehyde |
| abstract | The invention relates to the technical field of compound organic synthesis, specifically a preparation method of β-hydroxyethyl cinnamaldehyde, step 1: adding a substrate into a reaction vessel; step 2: adding a solvent and a copper catalyst into the reaction vessel , amine, peroxide, formic acid; step 3: heating the reaction vessel to cause a heating reaction in the reaction vessel to obtain a preform; step 4: post-processing the preform to obtain β-hydroxyethyl cinnamaldehyde. Compared with the prior art, the present invention uses tetrahydrofuran and benzaldehyde as a substrate to synthesize β-hydroxyethyl cinnamaldehyde in one step, while raw materials such as tetrahydrofuran and benzaldehyde and other reactants and catalysts are cheap and easy to obtain, and the production of the present invention The method is simple, one-step synthesis, and the substrate is universal, and heterocyclic rings can also be reacted. |
