Abstract

The photochemistry of 11,12‐bis(aminomethyl)‐9,10‐dihydro‐9,10‐ethenoanthracene (4) was investigated in solution and in the solid state. Direct irradiation of 4 gave the singlet state photoproduct 5, whereas the triplet derived photoproduct could only be obtained by irradiating the bis(hydrochloride) salt of 4 in the presence of xanthen‐9‐one to give semibullvalene 6‐(HCl)~2~. Solid state photolysis of 4 resulted in the formation of the pyrrole derivative 7, which is likely due to steric interactions in the solid state.
