Beschreibung

Allgemeine Beschreibung

Cesium hydrogencarbonate is used as a source of bicarbonate ions.

Anwendung

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.
