Application

Diethyl carbonate may be used in the following studies:
  • Synthesis of β-enamino esters.
  • Synthesis of carbamates and unsymmetrical alkyl carbonates, via reaction with aliphatic amines or alcohols by using a hybrid organic-inorganic material prepared by anchoring TBD to MCM-41 silica.
  • As solvent in ruthenium catalyzed direct functionalisation of arene C-H bonds by aryl halides.
  • To compose the commercial liquid electrolyte for lithium ion batteries.
  • Homogeneous alkoxycarbonylation of cellulose.
