  Phthalate plasticizers covalently linked to PVC via copper-free or copper catalyzed azide-alkyne cycloadditions

  摘要：

  Plasticization of PVC was carried out by covalently linking phthalate derivatives via copper-free (thermal) or copper catalyzed azide-alkyne cycloadditions. Di(2-ethylhexyl) phthalate derivatives (DEHP-ether and DEHP-ester) were synthesized and appended to PVC at two different densities. The glass transition temperatures of the modified PVC decreased with increasing content of plasticizer. PVC-DEHP-ether gave lower glass transition temperatures than PVC-DEHP-ester, reflecting the enhanced flexibility of the ether versus ester linker. (C) 2017 Elsevier Ltd. All rights reserved.

  Aerobic oxidation with N-hydroxyphthalimide catalysts in ionic liquid

  摘要：

  N-Hydroxyphthalimide (NHPI)-catalyzed aerobic oxidations in the ionic liquids were examined for the first time. Both NHPI and its ionic derivative, 3-pyridinylmethyl-N-hydroxyphthalimide (Py-NHPI), were found to have better performance in the ionic liquid than in the conventional organic solvents for the aerobic oxidation of N-alkylamides to imides. On the other hand, Py-NHPI was found to be a much better catalyst than NHPI for the aerobic oxidation of benzylic compounds in the ionic liquid. (c) 2005 Elsevier Ltd. All rights reserved.
