Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.
