meso-octyl-substituted tetrabenzoazaporphines and their zinc complexes: Synthesis and spectra
摘要:
Zinc complexes of meso-trioctyltetrabenzomonoazaporphine and trans- and cis-meso-dioctyltetrabenzodiazaporphine were prepared by the reaction of 1,3-diiminoisoindoline with excess capric acid in the presence of zinc oxide. The corresponding metal-free porphines were prepared by treatment of the metal complexes with sulfuric acid. The spectra of the azaporphyrins prepared were examined.
