Synthesis and Oxidation ofCobalt(II) Pheophytin-α Complex

Synthesis and Oxidation ofCobalt(II) Pheophytin-α Complex

The mechanism of oxidation of natural pheophytin-a incorporated with cobalt as the central metal ion has been investigated. Natural pheophytin-aextracted from spinach was metallated with cobalt(II) to form the complex, cobalt(II) pheophytin-α [Cophe]. The complex was characterized by Ultraviolet and...
