VerwendenCesium hydroxide hydrate is used as a catalyst for the conversion of alcohols substituted anilines and heterocyclic amines undergo an addition in NMP to phenylacetylene leading to functionalized enol ethers and enamines. It is also used in the chemoselective N-alkylation of secondary amines with alkyl halides.
