| 제목 | PS-Anchored Imidazole-based Ionic Liquids for Generating Diureas |
| 초록 | Urea and its substituted derivatives are playing important role in chemical industry for many decades [1]. However, for a long time, these useful substances have been prepared by the coupling reaction between amines and phosgene. In order to avoid using harmful agent, greener and economic routes have been investigated by numerous researchers. During the last decades, enormous works have been done on finding a homogenous catalyst for this transformation, however, heterogeneous catalysts still have not intensively developed – only a few active solid bases have been published such as CeO2, Cs2CO3 in NMP and PEG/KOH system [2]. Here we present a novel heterogeneous catalyst system comprising polystyrene-anchored matrices and basic ionic liquids as simple but highly regenerative catalyst for the synthesis of diureas from direct coupling reactions of various amines and CO2.
