title: Switching the Z/E selectivity in the palladium(II)-catalyzed decarboxylative Heck arylations of trans-cinnamaldehydes by solvent.
abstract: The Z/E selectivity of Pd(II)-catalyzed decarboxylative Heck-type arylations of trans-cinnamaldehydes can be controlled readily by switching the reaction solvent. Depending on the type of solvent used, each of the two isomeric products can be obtained with good to excellent Z/E ratio. In THF, Z-isomers were formed preferentially, whereas DMF provided the E-isomers predominantly.
