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

The reaction of 1,3-dithiolane derivatives of ketones having a-hydrogen with lithium diisopropylamide results in fragmentation to the corresponding thioketone followed by further conversion in a few steps to the other intermediate species which, on trapping with alkyl halide, leads to a vinylic sulfide and/or a sulfide bearing a secondary alkyl group.
