Abstract
Tandem reactions via electrocatalytic annulations have emerged as a strategy for the construction of heterocycles. Herein, a two‐component electrochemical annulation via sequential reduction, oxidation, and condensation steps to synthesize valuable benzimidazoles motifs is reported. This reaction, which utilizes electricity as both the oxidants and reductants, tolerates a broad range of functional groups. Detailed mechanistic studies including control experiments, cyclic voltammetry (CV) analysis, and key reaction intermediate characterization, reveals an intermolecular electrochemical redox/cyclization pathway.
期刊介绍:
Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry.
The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
