Title: [Intermediate reduction products of porphyrins and their structure]. Author: Shul'ga AM, Siniakov GN, Gurinovich GP. Journal: Biofizika; 1978; 23(1):5-10. PubMed ID: 623822. Abstract: It was shown on the basis of NMR-H spectra that the addition of proton to dianions of Zn-octaethylchlorine, Zn-octaethylporphin, and Zn-monoasaethioporphyrin results in the formation of products with the structure of alpha-dihydroflorine, alpha-florine, and gamma-florine respectively. This indicates that electron density greatly increases when the anions are formed in the centres which had a decreased density in the initial molecule.[Abstract] [Full Text] [Related] [New Search]
