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.
