trichloromethanesulfenyl chloride is described. The thus generated bis-propargylic trichloromethanesulfenates undergo spontaneous double [2,3]-sigmatropic rearrangement which leads to the formation of conjugated diallenic trichloromethyl sulfoxides in good to excellent yields.
摘要 描述了几种 2,4-二炔-1,6-二醇的制备及其与三氯甲磺酰氯的酯化反应。如此生成的双炔丙基三氯甲磺酸盐发生自发的双 [2,3]-σ 重排,导致以良好至极好的产率形成共轭二烯三氯甲基亚砜。
