利用10 mol%铜粉(0.3-1 μ m)在室温下实现末端炔烃和内部炔烃的区域选择性硼氢化。 24 种炔烃在不添加任何配体或添加剂的情况下被有效转化为乙烯基硼酸酯，产率高达 96%。
Regioselective hydroboration of terminal and internal alkynes is realized by using 10 mol% copper powder (0.3-1 mu m) at room temperature. 24 alkynes were efficiently converted into vinylboronates in up to 96% yield without addition of any ligand or additive.
