the reaction effectively. Based on these results, a possible reaction mechanism on the synergistic catalysis of DBU and the ionicliquid is proposed. In addition, the reaction of CS2, ethyleneoxide, and aniline catalyzed by the combination of DBU and the DBU‐derived ionicliquid also proceeds smoothly, which opens a hitherto unreported route to [1,3]dithiolan‐2‐ylidenephenylamine in a straightforward

An effective one‐pot method for the conversion of carbondioxide, ethyleneoxide, and amines to 3‐aryl‐2‐oxazolidinones has been developed. This one‐pot method consists of two parallel reactions and a subsequent cascade reaction between the two products of the corresponding parallel reactions. Notably, the binaryionicliquids of 1‐butyl‐3‐methyl‐imidazolium bromide and 1‐butyl‐3‐methyl‐imidazolium
