Palladium‐Catalyzed Isomerization of exo‐Methylenic Allylic Alcohols

Abstract Treatment of allylic alcohols containing a 1,1‐disubstituted alkene with a palladium catalyst and hydrogen gas (1 bar) results in facile isomerization to their corresponding trisubstituted ( E )‐allylic alcohols, along with small amounts of the corresponding hydrogenated products.
