The reactions of a variety of 1,3-bis(phenylthio)propanes with butyllithium have been shown to produce cyclopropyl phenyl sulfides in good to high yields. A new and convenient in situ preparation of 1-lithiocyclopropyl phenyl sulfide can be readily carried out by treating 1,3-bis(phenylthio)propane with 2 equiv. of butyllithium at 0 °C in THF. The reaction with electrophiles proceeds in good yield

β-Stannyl carbonylcompounds, when treated with Lewis acids, afforded cyclopropane derivatives or ketones, and the reaction was applied to the synthesis of β,γ-enones from α, β-enones.
