Over the past decades, organometallic complexes with precious elements, such as ruthenium and iridium, are widely used as visible-light photoredox catalysts. Recently, more and more complexes based on earth-abundant and inexpensive elements have been used as sensitizers in photochemistry. Although the photoexcited state lifetimes of iron complexes are typically shorter than those of traditional photosensitizers, the utilization of iron catalysts in photochemistry has sprung up owing to their abundance, low price, nontoxicity, and novel properties, including exhibiting ligand to metal charge transfer states. This concept focuses on recent advances in light-driven iron catalysis in organic transformations, including iron/photoredox dual catalysis, light-induced iron photoredox catalysis and light-induced generation of active iron catalysts. The prospect for the future of this field is also discussed.
在过去几十年中，含有钌和铱等贵金属元素的有机金属配合物被广泛用作可见光光氧化还原催化剂。最近，越来越多基于储量丰富且价格低廉元素的配合物被用作光化学中的敏化剂。尽管铁配合物的光激发态寿命通常比传统光敏剂的短，但由于其储量丰富、价格低廉、无毒以及具有包括配体到金属电荷转移态在内的新颖性质，铁催化剂在光化学中的应用如雨后春笋般涌现。本文概念聚焦于光驱动铁催化在有机转化中的最新进展，包括铁/光氧化还原双催化、光诱导铁光氧化还原催化以及光诱导活性铁催化剂的生成。同时也讨论了该领域的未来前景。
