The bisdienophilic (hemiporphyrazinato)nickel complexes 1a-d bearing various alkoxy groups were synthesized from diiminoisoindoles 9a-d, diaminopyridines 10a, d, and nickel acetate. Reaction of 1a-d with an excess of pentaene 3 delivered the macrocyclic bisdienes 2a-d. The hemiporphyrezines were characterized by 1H- and 13C-NMR spectroscopy. The NMR spectra of the 1,6,16,21-tetrabutoxy-substituted
