Ligand-free hydroboration of alkynes catalyzed by heterogeneous copper powder with high efficiency

Zhao, Jie,Niu, Zhiqiang,Fu, Hua,Li, Yadong

supporting information, p. 2058 - 2060 (2014/03/21)

Regioselective hydroboration of terminal and internal alkynes is realized by using 10 mol% copper powder (0.3-1 μm) at room temperature. 24 alkynes were efficiently converted into vinylboronates in up to 96% yield without addition of any ligand or additiv
