The often high cost of bespoke transition-metal-containing and organic photocatalysts inspires the development of a practical and green method by which photocatalysts can be recovered and reused through multiple reaction iterations. Herein, we showcase a general method to access novel solid-supported photocatalysts (SSPCs) that are recoverable by simple filtration. Proof-of-concept SSPCs were successfully utilized in two representative photoredox-catalyzed transformations with recycled catalysts showing no loss in activity in iterative reaction runs. Additionally, the viability of one of these SSPCs in a multi-gram scale reaction was demonstrated with the development of an easily replicated flow system.

开发用于有机合成的可回收固体支撑光催化剂的通用程序

定制的含过渡金属和有机光催化剂的成本通常很高，这激发了人们开发一种实用的绿色方法，通过这种方法可以通过多次反应迭代来回收和再利用光催化剂。在这里，我们展示了一种获取新型固体支撑光催化剂（SSPC）的通用方法，该催化剂可通过简单过滤回收。概念验证 SSPC 已成功用于两个具有代表性的光氧化还原催化转化，其中回收的催化剂在迭代反应运行中没有表现出活性损失。此外，通过开发易于复制的流动系统，证明了其中一种 SSPC 在多克规模反应中的可行性。
