  通过功能化和立体络合推进可回收芳族聚酯的开发

  摘要：

  使用环氧化物作为结构单元能够制备一系列具有功能化部分的可回收芳族聚酯，这推动了广泛的聚合后改性以获取增值材料。立体络合聚合物的形成具有增强的热稳定性和结晶度，无规共聚物表现出类似聚烯烃的机械性能。

• One-Pot Synthesis of Benzo[<i>e</i>]1,4-oxathiepin-5-ones under Solvent-Free Condition via Self-Promoted Thiolysis of 1,2-Epoxides

  Under solvent-free conditions, thiosalicylic acid (2) efficiently self-promotes the thiolysis of 1,2-epoxides 1, anti-stereoselectively and generally totally beta-regioselectively. The resulting beta-hydroxysulfide products 3 have been obtained in very good yields. Benzo[e]1,4-oxathiepin-5-ones 4 have been easily prepared in a regio- and diasteroselective manner and in satisfactory yields under SFC by a one-pot protocol including nucleophilic ring opening of 1,2-epoxides 1 by thiosalicylic acid (2) and thermally induced lactonization of beta-hydroxy arylsulfides 3. Solvent-free condition and the absence of any catalyst make this procedure atom-economical and environmentally friendly.
