N'-ethoxymethylene-meso-tetraphenylporphyrin and hydroxylamine-O-sulfonic acid or by direct cyanation with cyanogen bromide. Its metallation is rapid and concommitant cleavage of the N-substituent was observed. Such a reactivity can be used for rapid introduction of short-lived radionuclides into porphyrins. The crystal structure of N-cyano-meso-tetra-p-tolylporphyrin was determined. The macrocycle is ruffled, the pyrrole
