Mechanoredox chemistry is a rapidly evolving field at the intersection of mechanical forces and chemical reactions. Herein, we have reported a vicinal dibromination of unsaturated hydrocarbons using piezoelectric material (LiTiO) as a redox catalyst. Furthermore, the reaction can be efficiently scaled up to 10 mmol and performed under an air atmosphere at room temperature without solvents or external reductants, and LiTiO can be reused multiple times without a structural change.
机械氧化还原化学是一个在机械力和化学反应交叉领域迅速发展的研究方向。在此，我们报道了使用压电材料（LiTiO）作为氧化还原催化剂对不饱和烃进行邻位二溴化反应。此外，该反应可以有效地放大到10 mmol规模，并且在室温下的空气氛围中无需溶剂或外部还原剂即可进行，而且LiTiO可以多次重复使用而不发生结构变化。
