Herein, we disclose that electrochemical stimulation induces new photocatalytic activity from a range of structurally diverse conventional photocatalysts. These studies uncover a new electron-primed photoredox catalyst capable of promoting the reductive cleavage of strong C(sp )-N and C(sp )-O bonds. We illustrate several examples of the synthetic utility of these deeply reducing but otherwise safe and mild catalytic conditions. Finally, we employ electrochemical current measurements to perform a reaction progress kinetic analysis. This technique reveals that the improved activity of this new system is a consequence of an enhanced catalyst stability profile.
在此，我们揭示了电化学刺激能从一系列结构多样的传统光催化剂中诱导出新型光催化活性。这些研究揭示了一种新型的电子引发光氧化还原催化剂，它能够促进强 C(sp )-N 和 C(sp )-O 键的还原断裂。我们举例说明了这些具有深度还原能力的、但在其他方面安全温和的催化条件的一些合成应用。最后，我们采用电化学电流测量进行反应进程动力学分析。该技术表明，该新体系活性的提高是由于催化剂稳定性得到改善的结果。
