Aniline compounds are important organic intermediates and basic chemical raw materials,widely applied in research fields such as pharmaceuticals,agrochemicals,dyes,and functional materials.The development of efficient and versatile synthesis of aniline derivatives is one of the research hotspots that have been attracting much attention.In the past few decades,the study of transition metal-catalyzed synthesis of aniline derivatives from aryl halides has attracted significant attention from chemists due to its advantages of broad substrate applicability,good functional group compatibility,and high reaction selectivity.This review summarizes the research progress in transition metal-catalyzed synthesis of aniline derivatives from aryl halides,including:(1)palladium-catalyzed synthesis of aniline derivatives from aryl halides;(2)copper-catalyzed synthesis of aniline derivatives from aryl halides;(3)nickel-catalyzed synthesis of aniline derivatives from aryl halides.
