A CONVENIENT MATHOD FOR PREPARATION OF 1-(METHYLTHIO) AND 1-(PHENYLTHIO)VINYLLITHIUM REAGENTS

Article abstract of DOI:10.1246/cl.1982.593

1-(Methylthio) and 1-(phenylthio)vinyllithiums were prepared by the treatment of the corresponding 2-methoxyethyl sulfides with twice molar amounts of butyllithium in the presence of N,N,N',N'-tetramethylethylenediamine (TMEDA). β-Alkylthio-β,γ-unsaturated alcohols were obtained in good yields by the reaction of the lithium salts with aldehydes.
