Phenyl 1-(trimethylsilyl)propadienyl sulfide undergoes a hydroalumination with diisobutylaluminum hydride (DIBAH) or lithium butyl(diisobutyl)aluminum hydride (BL-DIBAH). The adduct anion derived from DIBAH is regioselectively trapped with carbonyl compounds at the position α to the phenylthio moiety to give 1,3-dienes as Peterson olefination products; the anion derived from BL-DIBAH is trapped at
苯基 1-(三甲基甲硅烷基)丙二烯基硫化物与二异丁基氢化铝 (DIBAH) 或丁基(二异丁基)氢化铝锂 (BL-DIBAH) 进行氢铝化。衍生自 DIBAH 的加合物阴离子在苯硫基部分的 α 位被羰基化合物区域选择性地捕获,得到 1,3-二烯作为 Peterson 烯化产物;来自 BL-DIBAH 的阴离子被捕获在苯硫基部分的 γ 位置,得到 3-buten-1-ols。同一受体上的甲硅烷基金属化和锡铝化反应也作为等效反应进行了简要研究。
