## Abstract Palladium on carbon (10β% Pd/C) efficiently catalyzes the (retroβ)Michael addition of activated methylene compounds **2a**β**d**, such as malononitrile (**2b**), to monoβ and doubly activated styrenes **1a**β**h** to give the adducts **3a**β**l**. The scope and limitations are described
In the presence of catalytic amounts of cesium hydroxide (CsOH.H20), alcohols, substituted anilines and heterocyclic amines undergo an addition in NMP to phenylacetylene leading to functionalized enoi ethers and enamines. Anilines add to styrene (90-120Β°C, 12-14 h) leading to N-substituted anilines
