제목 Sulfoxide-based vinyl group protection strategy: A Facile post-polymerization modification method
초록 We report the introduction of a vinyl group into a polymer simply through the sulfoxide-based protection-deprotection, for the first time to our best knowledge. When sulfoxides are present next to an electron withdrawing groups, they can be easily removed with heat, forming vinyl groups. Based on this concept, we protected the alpha site of methacrylate with phenyl sulfoxide which can be thermally deprotected to form a methacrylic group. To prove this concept, we synthesized sulfoxide-protected (SP) polymers via ATRP using specifically designed SP monomer and initiator. The methacrylate-functionalized polymers were prepared by deprotecting the SP-polymers at 110 oC in anisole. The polymers were characterized by SEC, 1H NMR spectroscopy, MALDI-TOF-MS and ESI-Q-TOF MS. The vinyl functionality was confirmed as more than 96%. This concept exhibits an efficient way to introduce vinyl group into polymer with a great potential in macromolecular engineering.
