合成了二氢化卟啉钴配合物，并进行了电化学研究。配合物的单电子还原在中心金属处进行，以提供Co（I）物种;相反，对于非氢化的卟啉钴（II）配合物，单电子还原得到配体还原的自由基阴离子物种。单电子还原物种与烷基卤化物的反应性表现出明显的差异之间的配合物。卟啉的β-位的氢化使得可以产生具有比配体还原的自由基阴离子物种更高的反应性的中心钴还原物种。
The dihydrogenated porphycene cobalt(II) complex was synthesized and electrochemical experiments were carried out. The one-electron reduction of the complex proceeded at the central metal to afford the Co(I) species; in contrast, for the non-hydrogenated porphycene cobalt(II) complex, the one-electron reduction gave the ligand reduced radical anion species. The reactivity of the one-electron reduced species with alkyl halides showed clear differences between the complexes. Hydrogenation of the β-position of the porphycene makes it possible to generate a central cobalt reduced species possessing a higher reactivity than the ligand reduced radical anion species.
