Transmetallation of a Lithium Porphyrin with Iron(II)

Synthesis and characterization of the iron(III) derivative of the 2,3,7,8,12,13,17,18-octabromo-meso-tetrakis(N-methylpyridium-4-yl)porphyrin was accomplished via metal metathesis of the lithium porphyrin and iron(II) ion. Preliminary molecular orbital analysis of the iron(II) and iron(III) derivatives demonstrate that the iron(III) porphyrin exists at a lower energy state
