General description

Cesium acetate is an inorganic salt. It has been reported to change the surface of kaolinite by undergoing intercalation under various reaction conditions.[1] It modifies the catalytic activity of MCM (Mobil Composition of Matter) -41 and MCM-48-type mesoporous molecular sieves by undergoing ion exchange with cesium cations and impregnation on their surfaces.[2]

Application

Cesium acetate may be used for the inversion of secondary alcohols to afford inverted acetates.[3] It can also be used for the inversion of cyclopentyl and cyclohexyl alcohols.[4]
