Abstract BODIPYs have a well‐established role in biological sciences as chemosensors and versatile markers due to their chemical reactivity, which allows for fine‐tuning of photophysical characteristics. In this work, we combined the unique reactivity arylazo sulfones with advantages “sunflow” reactor develop fast, efficient, method photochemical arylation other chromophores. This approach resulted red‐shifted emitting fluorophores extended electronic delocalization at 3‐ 5‐positions BODIPY core. represents an advantageous functionalization compared existing strategies.

Abstract We present a novel and highly efficient method for synthesizing polyfunctionalized 1,2,4‐triazoles. This approach leverages visible light arylazo sulfones in combination with N ‐vinyl amides, the environmentally friendly solvent ethyl acetate. Remarkably, reaction proceeds without need (photo)catalysts, ensuring near‐perfect atom economy producing only water as by‐product. exhibits excellent functional group tolerance can be scaled both batch continuous‐flow processes.
