摘要

报告了一种无金属共轭有机聚合物（TPA-PQ）催化的分子内 C-H 功能化策略，用于在光和氧气存在下合成咪唑烷类化合物。这种异相催化方案是传统金属光催化策略的替代方案。DA-COP (TPA-PQ)包含作为供体单元（D）的 TPA 和作为受体单元（A）的菲醌衍生物，从而有助于共轭体系中的电子移动。TPA-PQ 具有出色的催化活性、稳定性和可重复使用性。

A metal-free route to substituted imidazolidines via ring-opening cyclization (ROC) of activated aziridines with N-benzylanilines: DA-COP catalyzed photo-oxidative C–H activation†

A metal-free, conjugated organic polymer (TPA-PQ)-catalyzed intramolecular C–H functionalization strategy for the synthesis of imidazolidines in the presence of light and O₂ is reported. This heterogeneous catalytic protocol is an alternative to the traditional metal-based photocatalysis strategy. DA-COP (TPA-PQ) contains TPA as the donor unit (D) and a phenanthrenequinone derivative as the acceptor unit (A), thus helping the electron movement in the conjugated system. TPA-PQ has shown excellent catalytic activity, stability, and reusability.
