Facile Synthesis of Ureas in Ionic Liquid

Department of Chemistry, Zhejiang University(Campus Xixi), Hangzhou 310028

Received Date: 29 September 2003

The reaction of isocyanates with aliphatic and aromatic amines in the 1-n-butyl-3- methylimidazolium tetrafluoroborate (bmimBF₄) ionic liquid in good to excellent yields is described. Due to its insolubility, the desired urea solids could be recovered by simple filtration from the ionic liquid after reaction.
