- 요약Cascade metathesis reactions using Grubbs-catalysts are intramolecular reorganization reactions between two unsaturated bonds to produce a conjugated 1,3-diene or triene. This cascade relay metathesis process that occurs among adjacent unsaturated bonds has driven new insights into the preparation of polymers with diverse side groups, telechelic structures, and degradability. However, the usage of this efficient cascade metathesis has not been well-studied with respect to other aspects of metathesis polymerization. The research reported in this thesis explores the design and application of various functional enyne reagents to mediate polymer degradation, ruthenium metal residue removal, and cyclic topology control of metathesis polymerization. The unique reactivity of a terminal alkyne towards ruthenium Fisher carbenes makes it a directing group to promote selective and rapid transfer reactions intramolecularly. Utilizing this unexpected metathesis reaction, different enyne molecules (Chapter 2) or diyne molecules (Chapter 3) are shown to copolymerize with cyclic enol ethers with low strain energy to give degradable alternating copolymers. Additionally, a fluorous enyne molecule is able to efficiently terminate the ruthenium active chain-end in common ROMP polymers to facilitate ruthenium removal via straightforward sequestration methods (Chapter 4). In addition, the enyne derivatives can be utilized to give cyclic Grubbs-type initiators to afford cyclic macromolecular structures through ring-expansion metathesis polymerization (REMP) (Chapter 5). Overall, functional enyne reagents and monomers demonstrate significant versatility in the manipulation of macromolecular reactivity and topology to extend the potential applications of metathesis polymerization.
