Synthesis of Stereoregular Telechelic Poly(phenylacetylene)s: Facile Terminal Chain-End Functionalization of Poly(phenylacetylene)s by Terminative Coupling with Acrylates and Acrylamides in Rhodium-Catalyzed Living Polymerization of Phenylacetylenes.

摘要: Various α,β-unsaturated carbonyl compounds, such as acrylates and acrylamides, were quantitatively introduced to the terminal chain end of poly(phenylacetylene)s by C-C bond formation with organorhodium(I) species formed in living polymerization phenylacetylenes a rhodium-based multicomponent catalytic system that we have recently developed, when these compounds used terminating reagents. This enables facile versatile synthesis stereoregular telechelic various functional groups at both initial ends because components aryl boronic acid derivatives initiators our are initiating resulting polymer.
