Diels-Alder reaction of tribenzo[b,g,l]thiopheno[3,4-q]porphyrazine as a new path for porphyrazine core modification
Diels-Alder reaction between tribenzo[b,g,l]thiopheno[3,4-q]porphyrazine and dimethyl acetylenedicarboxylate at ca. 200 degreesC produced a substituted tribenzo[b,g,l]porphyrazine and 3:1 unsymmetrically substituted phthalocyanine, which were characterized by UV-VIS, MCD, NMR, and mass spectroscopies.
