the direct photochemical arylation of furan with aryldiazonium salts. The synthesized supported photocatalyst was used in batch reactions under heterogeneous conditions with different aryl diazonium salts, and its recovery and recycle were demonstrated for up to three times. The immobilized photocatalyst was then loaded in a packed-bed reactor and used under continuous flow conditions. The flow reaction
曙红Y是最常用的光氧化还原催化剂有机染料之一,固定化后作为均相和非均相光催化剂广泛用于光化学反应。将曙红Y固定在固体载体上具有许多优点,例如光催化剂回收和再利用的可能性以及在流动条件下使用的可能性。在本文中,我们报告了曙红 Y 在 Merrifield 树脂上的固定化及其在芳基重氮盐直接光化学芳基化呋喃中的应用。合成的负载型光催化剂与不同的芳基重氮盐在非均相条件下用于间歇反应,并且其回收和循环被证明了高达3次。然后将固定化的光催化剂装入填充床反应器中并在连续流动条件下使用。流动反应可以在很短的反应时间内以比间歇式更高的生产率和时空产率获得芳基化产物。
