Convenient preparation of trans-arylalkenes via palladium(II)-catalyzed isomerization of cis-arylalkenes

A convenient method for the isomerization of cis-arylalkenes to their trans isomers using a palladium(II) catalyst is described. The reaction conditions are mild and general across a range of arylalkenes. The synthesis of a traps-resveratrol derivative from a mixture of alkene isomers was also completed.
