摘要
Simple, clean, safe, reproducible, and practical describes the synthesis of disubstituted urea derivatives, which are effectively synthesized from amines and carbon dioxide with a CsOH/ionic-liquid catalyst system. The products are easily separated and the catalytic system can be reused without deactivation (see picture).
