Sodium percarbonate (2Na2CO3·3H2O2, sodium carbonate-hydrogen peroxide, SPC), an easily accessible and bench-stable hydrogen peroxide-solid adduct based on inorganic salt, was efficiently used as a solid hydroxylating reagent for the ipso-hydroxylation of arylboronic acids under mild conditions, affording the corresponding phenols in an excellent manner at a fast rate. Moreover, a solvent-free solid-state
过碳酸钠(2Na 2 CO 3 ·3H 2 O 2,碳酸钠-过氧化氢,SPC)是一种易于获取且实验室稳定的基于无机盐的过氧化氢-固体加合物,可有效用作 ipso 的固体羟基化试剂-在温和条件下羟基化芳基硼酸,以极快的速度以极好的方式提供相应的酚类化合物。此外,还展示了使用 SPC 进行芳基硼酸氧化羟基化的无溶剂固态反应体系。此外,成功地进行了后续的苄基卤化物处理,为在一锅串联反应系统中制备苄基苯基醚提供了一条替代合成路线。
