Caesium acetate or cesium acetate is an ionic caesium compound with the molecular formula CH3CO2Cs often used in organic synthesis especially in Perkin synthesis; formation of unsaturated cinnamic-type acids by the condensation of aromatic aldehydes with fatty acids.[2]
It may be formed by the reaction of caesium hydroxide or caesium oxide with acetic acid.
