With the opening of azirine rings under the conditions of photoinduced electron transfer a new synthon for the synthesis of heterocycles is available.The formed 2-azaallenyl radical cation readily reacts with imine to form N-substituted imidazoles in reasonable yields.The synthesis of pyrrolophanes and imidazolophanes from bicyclic azirines is possible as well.With oligocyclic azirines complex heteroaromatic systems and even a porphyrin system can be built up. Key Words: Azirines / Imidazoles / Pyrrolophanes / Electron transfer reaction, photoinduced / 2-Azaallenyl radical cations
