Application
Cesium acetate is used in organic synthesis especially in the Perkin reaction to prepare unsaturated cinnamic-type acids. It is used in petroleum drilling fluids as an alternative to cesium formate. In organometallic chemistry, it is an additive for metal-ctalyzed coupling reactions. It is also used in the inversion of stereo chemistry of secondary alcohols.
