Popis: A novel 1,3-dioxopyrrolo[3,4-b]porphyrin (2) has been synthesized in 70% yield following a [4 + 2] cycloaddition reaction of pyrrolo[3,4-b]porphyrin 1 with (1)O(2). The new imide was used as a template to other 1,3-dioxopyrrolo[3,4-b]porphyrins and to the corresponding open counterparts. The UV/vis absorption spectra of the new compounds show significant red-shifts when compared with those of the nonsubstituted analogues. The structure of an imide derivative was confirmed by single-crystal X-ray diffraction.
