Aminotroponiminates (ATIs) are monoanionic ligands with an N,N‐binding pocket and a rigid, planar, unsaturated, C₇‐ring as a ligand backbone. Recent findings show that this ligand backbone can play an active role in coordination chemistry, redox reactions, and ligand‐centered reactivity of ATI complexes. Based on these results, ATIs have been recognized as redox‐active and cooperative ligands, which has implications for existing and potential future applications of ATI compounds in synthesis, catalysis, and materials science. The catalytic applications of ATI complexes are summarized in this Microreview, including results from the fields of hydroamination, epoxidation, cyanosilylation, ε‐caprolactone‐, olefin‐, epoxide‐, and epoxide/CO₂ (co‐)polymerization as well as electron transfer catalysis. Furthermore, recent advances in the use of ATI ligands for stabilizing heavy analogs of carbon oxo compounds are showcased.

氨基硝基苯胺的新观点：配位化学，氧化还原行为，协同性和催化作用

氨基苯甲酸（ATIs）是单阴离子配体，具有一个N，N结合袋和一个刚性，平面，不饱和C ₇环作为配体主链。最近的发现表明，这种配体主链可以在ATI复合物的配位化学，氧化还原反应和以配体为中心的反应性中发挥积极作用。基于这些结果，ATI被认为是具有氧化还原活性和协同作用的配体，这对ATI化合物在合成，催化和材料科学中的现有和潜在未来应用具有影响。该Microreview总结了ATI配合物的催化应用，包括加氢胺化，环氧化，氰基硅烷化，ε-己内酯，烯烃，环氧化物和环氧化物/ CO _{2领域的结果。}（共）聚合以及电子转移催化。此外，展示了使用ATI配体稳定碳氧代化合物的重类似物的最新进展。
