Abstract

The development of a sustainable catalytic system for red-light-induced photocatalysis is presented. The catalytic system consists of a helical carbenium ion-based organic photoredox catalyst (PC) that is capable of using low-energy red light (λ_max = 640 nm) for both photooxidations and photoreductions. Its successful applications in the aerobic oxidative hydroxylation of arylboronic acids and in the oxidation of benzylic C(sp³)–H bonds (reductive quenching), as well as in dual transition-metal/organocatalyzed C–H arylations and intermolecular atom-transfer radical additions (oxidative quenching) provide further support for its role as a versatile and efficient organic PC.

螺旋碳鎓离子基有机光氧化还原催化剂：在红光诱导反应中的多功能和可持续的选择。

摘要

介绍了可持续发展的催化系统，用于红光诱导的光催化。催化系统由基于螺旋碳鎓离子的有机光氧化还原催化剂（PC）组成，该催化剂能够使用低能红光（_λmax = 640 nm）进行光氧化和光还原。它成功地用于芳基硼酸的好氧氧化羟基化以及苄基C（sp ³）-H键的氧化（还原淬灭），以及双重过渡金属/有机催化的CH芳基化和分子间原子转移基团添加物（氧化猝灭）为其多功能和高效的有机PC的作用提供了进一步的支持。
