extensive applications such as corrosion inhibitors, antioxidants in gasoline, and intermediates for pharmaceuticals and agrochemicals.2,3 Among urea derivatives, 2imidazolidinone is widely used as an intermediate for the synthesis of medicines, toiletries, cosmetic products,4 and as delignification solvent and chemotherapeutic agents.5,6 It is also the key intermediate in the synthesis of 1,3-dim
2-乙二胺 (EDA) 与光气、三光气或二氧化碳。当使用光气时,该反应需要高压并导致严重的毒理学和环境问题。8-10 除了需要使用昂贵的原材料外,许多催化剂价格昂贵且对人体健康有害。因此,已经开发了涉及 EDA 与尿素反应 11 和有机碳酸酯(如碳酸二甲酯、碳酸二乙酯、碳酸亚乙酯和双(对碳甲氧基苯基)碳酸酯)的替代路线。 3,6,12-14 碳酸二甲酯 (DMC) 是一种安全、低成本、绿色环保的光气和其他羰基化剂的替代试剂1,15。最近,
