15 N‐labelling experiments and energy calculations on nitreno‐azines and ‐diazies are in agreement and lead to the theory that both ring contraction and ring expansion in hetarylnitrenes can be one‐step processes which are governed mainly by the energy differences between the reacting species and the products.
