Organoboron compounds have important synthetic value and can be applied in numerous transformations. The development of practical and convenient ways to synthesize boronate esters has thus attracted significant interest. Photoinduced borylations originated from stoichiometric reactions of alkanes and arenes with well-defined metal–boryl complexes. Now, photoredox-initiated borylations, catalyzed by either transition metal or organic photocatalysts, and photochemical borylations with high efficiency have become a burgeoning area of research. In this Focus Review, we summarize research on photoinduced borylations, especially emphasizing recent developments and trends. This includes the photoinduced borylation of arenes, alkanes, aryl/alkyl halides, activated carboxylic acids, amines, alcohols, and so on based on transition metal catalysis, metal-free organocatalysis, and direct photochemical activation. We focus on reaction mechanisms involving single-electron transfer, triplet-energy transfer, and other radical processes.

用于合成有机硼化合物的光诱导硼酸化

有机硼化合物具有重要的合成价值，可用于多种转化。因此，开发实用且方便的合成硼酸酯的方法引起了人们极大的兴趣。光致硼酸化源于烷烃和芳烃与明确定义的金属硼基配合物的化学计量反应。现在，由过渡金属或有机光催化剂催化的光氧化还原引发的硼酸化以及高效的光化学硼酸化已成为一个新兴的研究领域。在这篇焦点评论中，我们总结了光诱导硼酸化的研究，特别强调了最近的发展和趋势。这包括基于过渡金属催化的芳烃、烷烃、芳基/烷基卤化物、活化的羧酸、胺、醇等的光诱导硼化，无金属有机催化和直接光化学活化。我们专注于涉及单电子转移、三重态能量转移和其他自由基过程的反应机制。
