Recent advances in photocatalytic C-H amination to nitrogenous structures

Nitrogen-containing structures represent a significant branch exhibiting remarkable biological activity, surpassing non-nitrogen architectures. Given the vast array of nitrogen-containing compounds and their crucial role in the pharmaceutical industry, chemists have been motivated to devise efficient, cost-effective, and practical methods for C-N bond formation. Significant advancements have been achieved in this cutting-edge field over the past few decades. This review aims to encapsulate the latest progress in C-N bond formation via the photocatalytic C-H amination process. Initially, we provide a comprehensive introduction to C-H amination transformations. Subsequently, we categorize these photochemical conversions into two parts: intramolecular and intermolecular C-H amination. To elucidate the underlying principles of specific illustrative examples, we have carefully chosen and elaborated on the reaction mechanisms, representative experimental outcomes, and applications. Nitrogen-containing structures represent a significant branch exhibiting remarkable biological activity, surpassing non-nitrogen architectures. The review is organized into sections based on the various photo-induced catalytic systems employed. Within each section, we delve into the specific reaction conditions, the range of substrates used, and the underlying reaction mechanisms involved in photochemical C-H amination transformations.
