contributed to highlight the non‐innocent role played by the donor atom set in the control of the cyclometallation kinetics. The as‐prepared bis‐amido catalysts were found to be good candidates for the intramolecular hydroamination/cyclization of primary aminoalkenes. The ability of these compounds to promote such a catalytic transformation efficiently (by providing, in some cases, fast and complete substrate

氢胺化/环化的良好候选者。这些化合物有效地促进这种催化转化的能力(通过在某些情况下提供快速和完全的底物转化)构成了朝着催化体系迈出的重要一步,该催化体系可以在相对较低的催化剂负载量和较温和的反应条件下运行。动力学研究和底物范围研究,以及对实际系统的初步DFT计算,
