Transition-Metal- and Photocatalyst-Free Photoinduced Formation of Carbon–Pnictogen (–N, –P) Bonds

Abstract Pnictogens, classified within group 15 elements, play a pivotal role in the constitution of a diverse array of drug molecules, natural products, and functional materials. Recent research has increasingly prioritized the exploration of mild conditions for synthesizing C–Pnictogen (C–N and C–P) bonds, highlighting a growing emphasis on efficient and sustainable synthetic methodologies. This Short Review explores fundamental mechanisms, addresses constraints, and assesses diverse methodologies, underscoring the potential of photocatalyst- and transition-metal-free photochemical reactions in advancing sustainability. Divided into two segments, it encompasses recent advancements in reactions facilitating C–N and C–P bond formation. 1 Introduction 2 Carbon–Nitrogen (C–N) Bond Formation 3 Carbon–Phosphorus (C–P) Bond Formation 4 Summary and Outlook
