General description

Diethyl ether is a versatile organic solvent used in the fields of diesel engines, agriculture, food, chemical, biological, pharmaceutical, and medical industries.

Application

Diethyl ether can be used as a solvent in the:
  • Ring-opening polymerization of ε-caprolactone to synthesize polycaprolactone.
  • Rh-catalyzed C-H allylation of amides with allyl halides to synthesize allylated amides.
  • Photochemical α-bromination of aromatic and aliphatic carbonyl compounds with N-bromosuccinimide to synthesize α-brominated ketones.
