S-烷基,S-芳基和S-乙烯基硫代硫酸钠盐(Bunte盐)与Grignard试剂反应生成硫化物,收率很高。S-烷基邦特盐是由无味的硫代硫酸钠通过与烷基卤化物的S N 2反应制备的。开发了铜催化的硫代硫酸钠与芳基卤化物和乙烯基卤化物的偶联物,以得到S-芳基和S-乙烯基丁烯酸盐。该反应适合于多种结构的邦特盐和格氏试剂。重要的是,这种硫化物的途径避免了使用恶臭的硫醇原料或副产物。

A rhodium(III)‐catalyzed cross‐coupling of benzylthioethers and aryl carboxylic acids through the two directing groups is reported. Useful structures with diverse substituents were efficiently synthesized in one step with the cleavage of four bonds (CH, CS, OH) and the formation of two bonds (CC, CO). The formed structure is the privileged core in natural products and bioactive molecules. This

sulphoxides Ph·[CH2]n·SO·Me (n= 0–4) were compared in pyrolytic and mass spectrometric behaviour. On pyrolysis either β-elimination or rearrangement occurred, but similar effects were not observed in the massspectra. The attempted preparation of one of the sulphoxides actually yielded the next higher homologue by a complex series of reactions.
在热解和质谱分析行为中比较了亚砜Ph·[CH 2 ] n ·SO·Me(n = 0–4)。在热解过程中,发生了β-消除或重排,但在质谱图中未观察到类似的作用。通过一系列复杂的反应,尝试制备一种亚砜实际上产生了下一个更高的同系物。
