Treatment of Baylis-Hillman adducts 1 with bromo(dimethyl)sulfonium bromide, Br(Me 2 )S + Br À , in MeCN was found to stereoselectively afford (Z)-and (E)-allyl bromides 2. The reaction is rapid at room temperature, high-yielding, and highly stereoselective.
## Abstract A series of trisubstituted alkenes containing (__Z__)‐allylthio moieties as key structural units, that is, sodium (__Z__)‐allyl thiosulfates, symmetrical di(__Z__‐allyl) sulfides, and di(__Z__‐allyl) disulfides, unsymmetrical diallyl sulfides were prepared in moderate to good yields via
