General description
Cesium hydroxide is a strong base that can be used in organic synthesis, as a catalyst, and as an intermediate in the production of cesium compounds.
Application
Cesium hydroxide monohydrate can be used:
- As a catalyst to prepare unsymmetrical Bis-allyl ethers via dimerization of Baylis-Hillman adducts.
- As a dopant to fabricate vanadium oxide thin films as a hole extraction layer for perovskite solar cells.
- As an initiator for ring opening polymerization of monosubstituted oxiranes.
- As a promoter to synthesize secondary amines via chemoselective N-alkylation.
