The Zn/Barbier reaction of acid-washed zinc or zinc/silver couple with (Z)- or (E)-CF3CFCFI and aromatic aldehydes in DMF stereospecifically gives the (Z)- or (E)-allylic alcohol, CF3CFCFCH(OH)C6H5. Substituted aromatic aldehydes, which contain an electron-withdrawing group, undergo Barbier addition reaction. Substituted aromatic aldehydes, which contain an electron-releasing group, fail to undergo
