| Outline of Final Research Achievements |
Primary alcohol-selective acylation of primary-secondary mixed diols was investigated by using tetraarylphosphonium salts as a precursor of phosphonium betaines. It has been found that the selective acylation with the use of acid anhydrides proceeds smoothly in the presence of catalysts. In addition, carbon dioxide fixation catalyzed by tetraarylphosphonium salts was also examined. As a result of screening, the reaction of epoxides with carbon dioxide under atmospheric pressure enabled to afford desired cyclic carbonates in good yields.
