近年来,以过渡金属钌和铱络合物为代表的光催化剂的开发和应用为有机合成开启了新篇章,这些过渡金属光催化剂参与的光催化反应为化学键的构筑和有机转化提供了温和高效的新策略.为了丰富光催化剂的种类,拓宽光催化体系的适用范围,发展绿色可持续化学,近年来一些廉价易得的过渡金属比如铜、铁等被相继开发用作光催化剂.其中,铁催化剂因其无毒、种类丰富,并且具有独特的配体-金属电荷转移性质,在光催化合成领域大放异彩.依据反应类型对光诱导铁催化反应进行了综述,主要包括C—H键官能团化反应、C-C键官能团化反应、烯烃双官能团化反应、交叉偶联反应、脱羧官能团化反应、选择性氧化和还原反应.

In recent years,the development and application of transition metal ruthenium or iridium complexes based photocatalysts have opened up a new research field for organic synthesis,which provides mild and efficient strategies for the construction of chemical bonds and organic transformations.In order to enrich the types of photocatalysts,broaden the application scope of photocatalysis,and develop green and sustainable chemistry,some low-cost and easily available organometallic complexes with copper or iron were applied as photocatalysts recently.Iron-complexes feature non-toxicity,rich variety,and unique property of charge transfer from ligands to metals,which enable them show extraordinary capability in the field of photocatalytic synthesis.According to different reaction types,this review focuses on the recent development of photoinduced iron-catalysis in organic synthesis including C-H bond functionalization,C-C bond functionalization,bifunctionalization of alkenes,cross-coupling reaction,decarboxylative functionalization,selective oxidation and reduction.
