Article Abstract
C-N coupling is crucial for constructing amides and amines and involves various fields, including medicine, chemical industries, agriculture, and energy. With the rapid development of electrocatalytic C-N coupling and the continuous improvement of catalytic performance, this field has aroused extensive research interest. A comprehensive review is urgently needed to summarize the structure-activity relationship, key challenges, and future development directions. This review provides a concise overview of the recent advancements from nanocatalysis to single metal site catalysis for electrocatalytic C-N coupling reactions. We summarize the C-N coupling mechanisms using different nitrogen sources and further analyze the influences of various active metal centers and different coordination environments on the C-N coupling performance, thereby elucidating the structure-activity relationship. Moreover, we discuss the dynamic structural evolution of active metal sites during the reaction. Finally, we present current challenges and perspectives in this field. This review aims to provide valuable insights into the development of advanced nano/single metal site catalysts for electrocatalytic C-N coupling reactions along with a deeper understanding of catalytic mechanisms.

An unprecedented recyclable system of copper-catalyzed C-C/N coupling of isatins and DMSO without any oxidant and acidic/basic additive has been unlocked. The -isatins occur tandem -methylation and C5-methylthiomethylation in order, while -substituted isatins proceed C5-methylthiomethylation only. DMSO serves as Me and MeSCH sources as well as the solvent.

Using an Earth-abundant transition metal to mediate formation and splitting of C-C σ-bonds, in response to electrical stimuli, constitutes a promising strategy to construct complex organic skeletons. Here, we showcase how [ BuN][N] reacts with an isocyanide adduct of a tetrahedral and high-spin Ti complex, [(Tp )TiCl] (1), to enact N-atom transfer, C-N bond formation, and C-C coupling, to form a dinuclear complex, [(Tp )Ti{AdN(N)C-C(N)NAd}Ti(Tp )] (3), with two Ti ions bridged by a disubstituted oxalimidamide ligand ( Bu = -butyl, Tp = hydrotris(3--butyl-5-methylpyrazol-1-yl)borate, Ad = 1-adamantyl). Magnetic and computational studies reveal two magnetically isolated d Ti ions, and electrochemical studies unravel a reversible two-electron oxidation at -0.

We describe the first total syntheses of tabernanthine and ibogaline. Entry to these iboga alkaloid natural products is enabled by a thermal coupling of indoles and aziridines to furnish the requisite nosyl tryptamine starting materials. This route features a Friedel-Crafts type alkylation to form the key indole-isoquinuclidine C-C bond.
