| Outline of Final Research Achievements |
We studied the synthesis of macrocycles with the assistance of intramolecular hydrogen bondings under polymerization conditions by Suzuki-Miyaura coupling reaction of m-dibromo phenylene monomer having an hydrogen bonding unit between the two bromo groups and p-phenylenediboronic acid. The reaction proceeded in the mixture of water and THF, and oligomers with desired molecular weight were obtained as a major product when the ratio of water in the solvent was low. The crude products were separated by the preparative HPLC, and the mass analysis revealed the formation of the cyclic octamer.
