Abstract
We report an improved synthesis of porphine from d-tartaric acid, its conversion to complexes with Mg(II), V(IV), Mn(III), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II), their IR, UV-vis, NMR, XPS, and mass spectra, and single crystal X-ray diffraction structures of meso-tetrakis(n-hexyloxycarbonyl)porphyrin and (porphyrinato)manganese(III) bromide.
