The direct functionalization of the para-C(sp2)—H bond of anilines represents a significant research direction in organic synthesis. Conventionally, achieving selective functionalization at this position has predominantly relied on the pre-protection and activation of the amino group, a process that is not only step-intensive but also severely limits synthetic efficiency and step economy. In recent years, revolutionary progress has been made in this field. The development of diverse strategies, such as transition metal catalysis, organic photoredox catalysis, electrochemical synthesis, and metal-free catalysis, has successfully enabled the direct and highly selective modification of the para-C—H bond of anilines, fundamentally overcoming the limitations of traditional approaches. This review aims to systematically outline the research trajectory in this area, providing a detailed summary of the reaction design, mechanistic characteristics, and applications of these catalytic modalities in constructing carbon-carbon and carbon-heteroatom bonds, thereby offering a comprehensive account of the current development and key achievements in this pivotal synthetic transformation.

Key words: anilines, C—H functionalization, site-selectivity, transition metal catalysis, photoredox catalysis
