Photoredox catalysis has emerged as a powerful tool for the utilization of visible light to drive chemical reactions between organic molecules that exhibit two rather ubiquitous properties: colorlessness and redox-activity. The photocatalyst, however, requires significant absorption in the visible spectrum and reversible redox activity. This very general framework has led to the development of several new modes of reactivity based on electron and energy transfer steps between photoexcited catalyst states and various organic molecules. In the past years, major effort has been devoted to photoredox-catalytic aromatic substitutions involving an initial reductive activation of various aryl electrophiles by the photocatalyst, which opens a new entry into selective arene functionalizations within organic synthesis endeavors. This, however, has led to a unilateral emphasis of synthetic developments including catalyst modifications, substrate scope studies, and combinations with other chemical processes.

芳香取代有机光催化还原的机理研究。

光氧化还原催化已成为利用可见光驱动有机分子之间化学反应的有力工具，有机分子表现出两种普遍存在的特性：无色和氧化还原活性。然而，光催化剂需要在可见光谱中有显着的吸收和可逆的氧化还原活性。这种非常通用的框架基于光激发的催化剂状态与各种有机分子之间的电子和能量转移步骤，导致了几种新的反应模式的发展。在过去的几年里，人们一直致力于光催化氧化还原芳族化合物，包括光催化剂对各种芳基亲电子试剂的初始还原活化作用，这为有机合成中选择性芳烃官能化开辟了新途径。但是，这
