| Abstract: | Nucleophilic vinylic substitutions of (Z)-(β-(phenylsulfonyl)alkenyl)-phenyliodonium tetrafluoroborates 1 with tetrabutylammonium halides (Cl, Br, and I) proceed with exclusive retention of configuration at room temperature and afford (Z)-β-(phenylsulfonyl)vinyl halides 2 in high yields. |
