| Outline of Final Research Achievements |
Palladium-catalyzed reaction between a bifunctional electrophile (3-bromo-2,4-pentadienyl ester) and a bifunctional nucleophile (bis-malonate) provided polymers/oligomers having axially chiral allenic units in their main chains. Using a chiral palladium catalyst, optically active polymers/oligomers based on the axially chiral allenic moieties were obtained. The optically active polymers obtained from a bifunctional nucleophile having a siloxane junction could be converted to the corresponding monomeric allene quantitatively by the hydrofluoric acid treatment. The monomeric allene thus obtained was analyzed by the chiral HPLC to determine the stereoselectivity of the asymmetric polymerization process.
