The enynes HCCCH=CHCH2R (R = H, Me, OMe, NMe2, SMe), are converted into dimers by treatment with slightly more than two equivalents of butyllithium.The Z-configuration predominates in the dimers obtained after aqueous work-up.The lithiated enynes (R = H, Me, SMe) and acetylenic compounds LiCCCH2R (R = SMe, C6H5) add in an analogous way to the double bond of LiCCCH=CH2.
