Visible light irradiation of a solution of zinc octaethylporphin (ZnOEP) in the presence of acyl azide gives zinc complex of 5-acylamino-2,3,7,8,12,13,17,18-octaethylporphin together with a small amount of zinc complex of 21-acylamino-2,3,7,8,12,13,17,18-octaethylporphin. Zinc 5,10,15,20-tetraphenylporphin (ZnTPP) is coverted into zinc complex of 21-acylamino-5,10,15,20-tetraphenylporphin in a similar way. The pyrolysis of the <I>N</I>-acylaminated ZnOEP affords the rearrangement product in addition to ZnOEP, while <I>N</I>-acylaminated ZnTPP is converted into ZnTPP on heating. The spectroscopic properties of these photoproducts are given.
