(2-Nitro-5,10,15,20-tetraphenylporphyrinato)copper(II) (1) reacts with sodium benzylate or sodium methoxide in dimethylformamide by a novel aromatic nucleophilic substitution-nucleophilic addition sequence in which hydrogen is the leaving group to give the corresponding 2,2-dialkoxy-3-nitro-2,3-dihydroporphyrins which are efficiently converted into 2-alkoxyporphyrins in two steps; the overall sequence accomplishes a cine-substitution.
