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.

(13)C metabolic MRI using hyperpolarized (13)C-bicarbonate enables preclinical detection of pH. To improve signal-to-noise ratio, experimental procedures were refined, and the influence of pH, buffer capacity, temperature, and field strength were investigated. Bicarbonate preparation was investigated. Bicarbonate was prepared and
