A key reactive species , lithium borylcyanocuprate, was isolated and fully characterized in a one‐pot carboboration of alkynes. The carboboration involves a boryllithium, CuCN⋅2 LiCl, an ester‐substituted alkyne, and an organic electrophile (see scheme). By changing the reaction temperature, the syn / anti ratio of the carboborated products can also be changed.
