Copper(I) tert-butoxide is an alkoxide of copper(I). It is a white sublimable solid. It is a reagent in the synthesis of other copper compounds.^[1]

The compound was originally obtained by salt metathesis from lithium tert-butoxide and copper(I) chloride.^[2] An octameric form was obtained by alcoholysis of mesitylcopper:^[3]

8 CuC₆H₂Me₃ + 8 HOBu-t → 8 HC₆H₂Me₃ + [CuOBu-t]₈
