Reactions of 2-nitro-5,10,15,20-tetraphenylporphyrin with alkyl α-isocyanoacetates afford naphthochlorins (in addition to the expected pyrroloporphyrins) which undergo free radical dimerization; the X-ray structure of one such naphthochlorin dimer is repo

(2-Nitro-5,10,15,20-tetraphenylporphyrinato)nickel(II) reacts with α-isocyanoacetic esters in the presence of DBU to give the first β-fused pyrroloporphyrins, the pyrrole ring in the fused system being shown to undergo typical pyrrole-type chemistry; the corresponding zinc(II) complex affords a novel cyclopropanochlorin (characterized by X-ray crystallography), when treated with an α-isocyanoacetic ester.
