Abstract
Reactions of phthalimide with capric and stearic acids gave 1-[1-(1-oxo-1H-isoindol-3-yl)nonylidene]-2,3-dihydro-1H-isoindol-3-one and 1-[1-oxo-1H-isoindol-3-yl)heptadecylidene]-2,3-dihydro-1H-isoindol-3-one, respectively. The latter were heated with zinc(II) acetate to obtain zinc complexes of 5,15-dioctyl-and 5,15-dihexadecyltetrabenzoporphyrins. The same complexes were synthesized by reaction of 1-(1-oxo-1H-isoindol-3-ylmethylidene)-2,3-dihydro-1H-isoindol-3-one with capric or stearic acid in the presence of zinc(II) oxide. The corresponding free porphyrin ligands were obtained by treatment of the metal complexes with sulfuric acid.
