| description | The invention discloses a photocatalysis isoeneynol transposition isomerization process which comprises the following steps: under the condition of an initiator and blue light, isoeneynol shown in a formula (I) is subjected to transposition isomerization reaction in a mixed system of water and an organic solvent, the method comprises the following steps: adding a catalyst to a solvent to obtain E-pentyl-2-ene-4-alkyne-1-alcohol as shown in a formula (II) and Z-pentyl-2-ene-4-alkyne-1-alcohol as shown in a formula (III). According to the method, LED blue light irradiation is adopted, the photoelectric efficiency of the transposition isomerization process is improved, the acid consumption is reduced, and the safety of a process route is greatly improved.
本发明公开了一种光催化异烯炔醇的转位异构化工艺，包括：在引发剂和蓝光条件下，式(Ⅰ)所示的异烯炔醇在水和有机溶剂的混合体系中进行转位异构化反应，得到式(Ⅱ)所示的E-戊-2-烯-4-炔-1-醇和式(Ⅲ)所示的Z-戊-2-烯-4-炔-1-醇。该方法使用LED蓝光照射，提高了转位异构化过程的光电效率，降低了酸的用量，且大幅度提高了工艺路线的安全性。 |
