| 제목 | New observation of sulfur-promoted rearrangement during a polymerization of 5-substituted 1,3-oxathiolane-2-thiones. |
| 초록 | In previous study, we synthesized a stable polymer from 1,3-oxathiolane-2-thione with a alkyl sulfide substituent through ring opening polymerization(ROP). The substituent sulfide involved in the formation of a stable intermediate cation accompanying rearrangement of the alkyl substituent. Depolymerization of the prepared ROP polymer underwent in the presence KOtBu to yield 1,3-dithian-2-one. The presence of S-alkyl substituent at C-5 of 1,3-Dithian-2-one evidently proved the rearrangement. Since the ROP showed a living polymerization property, a block copolymerization was attempted. 1,3-Dithiane-2-one is a stable intermediate as a thiol processor and readily reduced. The thiol bound poly(ethylene oxide) would enhance electrochemical property through strong binding to a metal electrode. |
