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

Author affiliations

Abstract

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 additive.
