| Research Abstract |
Various new reactions and new metal coordination behaviors were revealed for mesa-aryl expanded porphyrins. Representative results are synthesis of novel heptaphyrins bearing direct pyrrole-pyrrole linkage in aqueous phase, extensive synthesis of meso-trifluoromethyl-substituted expanded porphyrins, sequential N-fusion reactions of heptaphyrin. Through these studies, we found that meso-aryl substituted hexaphyrins can take two types of stable conformations in solution depending on the meso-substituents. From 5,20-di(2-thienyl)-substituted hexaphyrin, we obtained new bis palladium complex formed via C-H bond activation of the 5-thienyl position.
