Special Issue Information

Dear Colleagues,

Palladium is definitely one of the most important transition metals in organic synthesis. The significance of palladium catalysts is evident by the fact that the Nobel Prize in Chemistry 2010 was awarded to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki “for palladium-catalyzed cross couplings in organic synthesis”. Though the cross coupling chemistry emerged during the 1970s, this research field is still evolving and considerable attention is being given to investigate new catalytic reactions such as stereo- and site-selective cross coupling, reactions with less reactive leaving groups, and cross coupling at C-H positions. This special issue will cover significant development in the exciting field of palladium-catalyzed cross coupling.

Title: Palladium-Catalyzed Synthesis of Pentafluorophenyl-Substituted Porphyins
Author: Toshikatsu Takanami
Affiliation: Meiji Pharmaceutical University, Japan
Abstract: An efficient direct introduction of perfluoroaromatic substituents, such as pentafluorophenyl group, to porphyrin core utilizing palladium-catalyzed cross-coupling reaction of brominated porphyrins with bis(penta¬ fluoro¬ phenyl)¬zinc will be described in the planning paper. It is well-known that the chemical, physical, and biological properties of porphyrins can be systematically regulated by the electronic, steric, and conformational environments of their peripheral substituents as well as the central metal ions. Pentafluorophenyl and related perfluoroaromatic groups are expected to greatly affect the electronic properties of porphyrin core. Only a few methods, however, have been available for the preparation of porphyrins bearing perfluoroaromatic groups. Most popular and classic approach to these fluorinated porphyrins involves multiple condensation reactions of the appropriate aldehyde(s) with various monopyrroles or substituted dipyrromethanes under acidic conditions, followed by oxidation of resulting porphyrinogen intermediates. Despite significant improvements with the introduction of new reaction conditions, these multiple condensation methods still suffer from low yields, significant side products, and tedious purification, thereby restraining efficient preparation of porphyrin derivatives bearing perfluoroaromatic groups. Thus, the development of an alternative approach to porphyrins bearing perfluoroaromatic groups with higher simplicity, generality, and practicality remains an important goal. To achieve this goal, we have developed a palladium-catalyzed coupling reaction of brominated porphyrins with bis(perfluorophenyl)Zn reagents, the method being a new and straightforward access to porphyrin derivatives bearing perfluoroaromatic groups. The details of these approaches we have developed will be described in the planning paper.
