Supported Au nanoparticles on TiO catalyze the unprecedented dehydrogenative disilylation of monosubstituted and 1,1-disubstituted allenes by Et SiH exclusively on the terminal double bond in a stereoselective manner. Treatment of the disilylation products with H O, in a one-pot operation also catalyzed by Au/TiO , leads to 3-alkylidene-1,2,5-oxadisilolanes, an unknown class of heterocyclic compounds, which are excellent scaffolds for the stereoselective synthesis of alkenes under Hiyama-type cross-coupling conditions.
负载在TiO上的金纳米颗粒以立体选择性方式，仅在末端双键上催化EtSiH对单取代和1,1 - 二取代丙二烯进行前所未有的脱氢甲硅烷基化反应。在同样由Au/TiO催化的一锅操作中，用H₂O处理甲硅烷基化产物，得到3 - 亚烷基 - 1,2,5 - 氧杂二硅戊环烷，这是一类未知的杂环化合物，它们是在日向型交叉偶联条件下立体选择性合成烯烃的优良骨架。
