Application

Triethyl orthoacetate can be used for the synthesis of:
  • Ordered mesoporous carbons for catalysis, electrochemistry and hydrogen storage applications.
  • Esters of phosphonic acids, carboxylic acids and phosphinic acids.
  • Ethyl alk-4-enoates by Johnson–Claisen rearrangement reaction.
  • Benzoxazoles, benzimidazoles and oxazolo[4,5-b]pyridines.
  • Quinazolin-4(3H)-one derivatives.
