Herein we reported the electrochemical hydroboration of alkynes by using B Pin as the boron source. This unprecedented reaction manifold was applied to a broad range of alkynes, giving the hydroboration products in good to excellent yields without the need of a metal catalyst or a hydride source. This transformation relied on the possible electrochemical oxidation of an in situ formed borate. This anodic oxidation performed in an undivided cell allowed the formation of a putative boryl radical, which reacted on the alkyne.
在此，我们报道了使用频哪醇硼酯（B Pin）作为硼源对炔烃进行电化学硼氢化反应。这种前所未有的反应体系适用于多种炔烃，无需金属催化剂或氢化物源即可获得良好至优异产率的硼氢化产物。这种转化依赖于原位形成的硼酸盐可能发生的电化学氧化。在无隔膜电解池中进行的这种阳极氧化能够形成一种假定的硼自由基，其可与炔烃发生反应。
