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.
在 N,N,N',N'-四甲基乙二胺 (TMEDA) 存在下,通过用两倍摩尔量的丁基锂处理相应的 2-甲氧基乙基硫化物来制备 1-(甲硫基)和 1-(苯硫基)乙烯基锂。β-烷硫基-β,γ-不饱和醇通过锂盐与醛的反应以良好的收率获得。
