species when compared with the corresponding photoproduct obtained from MCMAC. The C N photochemical cleavage is an unusual process in aliphatic 2 H -azirines. In the studied compounds, its preference over the commonly observed CC azirine-ring bond photocleavage is attributed to the presence of electron withdrawing substituents (methylcarboxy group in both azirines and also the chlorine atom in MCMAC), which
