In the presence of catalytic amounts of cesium hydroxide (CsOH · H2O), alcohols, substituted anilines and heterocyclic amines undergo an addition in NMP to phenylacetylene leading to functionalized enol ethers and enamines. Anilines add to styrene (90-120°C, 12-14 h) leading to N-substituted anilines in satisfactory yields.
