Copper(I) t-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
