A collection of (E)-1-alkenesulfenate anions were reduced by LiAlH4 at low temperature. The resulting enethiolates, with their E geometry intact, could be captured with chlorosilane to afford silicon protected enethiol ethers of thioaldehydes and thioketones. Reduction at a higher temperature prompts isomerization of the double bond.
一组(E)-1-烯烃硫酸盐阴离子在低温下被LiAlH4还原。生成的烯硫醇盐保持其E几何构型,可以与氯硅烷结合,从而得到硅保护的烯硫醇醚,这些醚来自硫醛和硫酮。在较高温度下的还原会促使双键异构化。
