Description and Uses
Diethyl carbonate (DEC) is generally used in the C-alkoxycarbonylation of enolate anions, aryl and alkyl cyanides. It reacts with 1,2-amino alcohols to yield corresponding 2-oxazolidinones. Additionally, DEC is also used as a component of electrolyte solution in lithium ion batteries.
