General description

Cesium hydrogencarbonate is used as a source of bicarbonate ions.

Application

Cesium hydrogencarbonate can be used as a base:
  • In the Ni-catalyzed hydroarylation of unactivated alkenes with arylboronic acids to synthesize arylated alkanes.
  • To synthesize 5-phenylthiazolamines by coupling thiourea with phenylacetones, phenylacetophenones, and β-tetralone in the presence of CBrCl3.
  • In the Pd-catalyzed hydroxycarbonylation of aryl halides.
  • In the regioselective alkylation of 2,4-dihydroxybenzyaldehydes and 2,4-dihydroxyacetophenones using alkyl halides to synthesize 4-alkylated products.
It can also be used as a catalyst for the:
  • Etherification of glycerol to oligomers.
  • Acetylation of primary alcohols and phenols to acetates using acetic anhydride.
