一般描述

1,3-二甲基-2-咪唑啉酮(DMI)是一种咪唑啉酮衍生物。据报道,它可通过最小化二烷基化副产物的形成并加速γ-丁内酯的单烷基化速率而起到促进剂的作用。已研究了通过使用DMI作为溶剂利用均相催化氢化将CO2转化为低级醇。

应用

1,3-二甲基-2-咪唑啉酮可用于:
  • 在1,2-双(三甲基甲硅烷基)苯的合成中作为六甲基磷酰三胺(HMPA)的替代溶剂。
  • 在亚胺的α-区域选择性异戊烯化过程中作为溶剂。
  • 作为流动相的组分用于纤维素的尺寸排阻色谱分析。

其他说明

在各种合成有机转化反应中作为溶剂。被研究可以用于形成功能性稳定羟基硅烷二基-过渡金属复合物,该复合物是由芳基硅烷光催化获得。
