Article abstract of DOI:10.1016/S0040-4039(00)95162-1

Treatment of S-alkyl thioesters with a reagent prepared from RCHBr2, Zn, TiCl4, and TMEDA in THF at 25 degC gives Z-alkenyl sulfides selectively in good to excellent yields.Using the alkylidenation method, ketene dithioacetals and enamines are produced fr
