The enynes HCCCHCHCH2R (R H, Me, OMe, NMe2 SMe), are converted into dimers by treatment with slightly more than two equivalent of butyllithium. The Zconfiguration predominates in the dimers obtained after aqueous workup. The lithiated enynes (R H, Me, SMe) and acetylenic compounds LiCCCH2R (R SMe, C6H5) add in an analogous way to the double bond of LiCCCHCH2.
的烯炔HCCCHCHCH 2 - [R(RH,Me中的OME,NME 2 SME),被转换成二聚物通过用稍微超过两个当量的丁基锂。所述ž configuration占优势在水性workup后得到的二聚体。锂化烯炔(RH,Me中,SME)和乙炔基化合物LiCCCH 2 - [R(RSMe的,C 6 H ^ 5)以类似的方式来LiCCCHCH的双键加2。
