Metalloporphyrins and metalloporphinones have been seen in a number of enzymes and involved in nitrogen metabolism, photosynthesis, and methanogenesis. The reduction of metalloporphyrins and metalloporphinones are achievable, but the site of reduction in either, the metal center or porphyrin core is still debatable. This prompted us to investigate the position of reduction in order to generate low valent metalloporphyrins and porphinones. The reduced porphyrins were characterized by spectroscopic and X-ray crystallographic methods. Previous work in our laboratory has generated low valent metalloporphyrins and porphinones by electrochemical reduction. In this work cobalt, manganese, and iron low valent metalloporphyrins were generated via chemical reduction and results were characterized by UV-visible, infrared spectroscopy, and X-ray crystallographic techniques.
