New borylcopper and borylzinc compounds were synthesized by transmetalation of boryllithium with metal halides. The 1,4‐addition of lithium borylbromocuprate [ B Cu(μ 2 ‐Br)Li(thf) 3 ] to 2‐cyclohexen‐1‐one as a boryl anion, followed by trapping of the resulting boron‐substituted copper enolate with Me 3 SiCl, afforded the γ‐siloxyallylborane.
