Abstract:

The synthesis of new porphyrins has become a major challenge, mainly due to their wide range of applications, including photochemical cells and photodynamic therapy (PDT). With the advent of one-pot processes for the synthesis of meso substituted porphyrins, the number of these compounds has increased considerably. Porphyrins with meso-thienyl groups can also be used as building blocks for new porphyrins. One way to functionalize these compounds is the Heck-Mizoroki and Sonogashira cross coupling reactions. We now propose the synthesis of meso-thien-2-yl-porphyrins functionalized with iodine, ready for cross-coupling reactions.
