efficient approach for the synthesis of fluorescent 2,3-naphthalimide derivatives has been developed from readily available starting materials via an intramolecular didehydro-Diels–Alder reaction, which proceeded well under room temperature, exhibiting a wide substrate scope and good functional group tolerance. The practicability of this methodology has been verified by one-step synthesis of the environmentally

A MnI complex coordinated with a redox non-innocent phenalenyl (PLY) ligand is reported for catalytic N-formylation of secondary amides (including late-stage diversification of pharmaceutics) and lactams with CO2 as C1 source at room temperature for the first time. A combined approach of experimental analysis and DFT calculations sketch the plausible radical-mediated pathway of an unconventional metal-ligand
据报道, Mn I络合物与氧化还原非无害苯二甲酰 (PLY) 配体配位,首次在室温下以 CO 2作为 C 1源催化仲酰胺(包括后期药物多样化)和内酰胺的 N-甲酰化时间。实验分析和 DFT 计算的组合方法描绘了一种非常规金属-配体合作的可能的自由基介导途径,涉及以配体为中心的自由基。
