Abstract

Treatment of S-alkyl thioesters with a reagent prepared from RCHBr2, Zn, TiCl4, and TMEDA in THF at 25°C gives Z-alkenyl sulfides selectively in good to excellent yields. Using the alkylidenation method, ketene dithioacetals and enamines are produced from 1,3-dithian-2-one and amides, respectively.
