General description
12-Crown-4 is a crown ether generally used as a ligand in coordination chemistry. It is also known as lithium ionophore because of its strong chelating property specific to lithium cation.
Application
12-Crown-4 can be used as:
- A promoter in the synthesis of poly(diethylsiloxane) (PDES) from monomer hexaethylcyclotrisiloxane using NaOH as a catalyst via anionic ring-opening polymerization.
- As an additive in the preparation of triarylmethane derivatives by palladium-catalyzed cross coupling reaction of aryl bromides with diarylmethane derivatives.
- A phase transfer catalyst in organic synthesis.
