Lithiumtert-butoxide is themetalorganic compound with the formula LiOC(CH3)3. A white solid, it is used as a strong base inorganic synthesis. The compound is often depicted as a salt, and it often behaves as such, but it is not ionized in solution. Both octameric[1] and hexameric forms have been characterized byX-ray crystallography.[2]
Lithiumtert-butoxide is commercially available as a solution and as a solid, but it is often generatedin situ for laboratory use because samples are so sensitive and older samples are often of poor quality. It can be obtained by treating tert-butanol with butyl lithium.[3]
As a strong base, lithiumtert-butoxide is easily protonated.
Lithiumtert-butoxide is used to prepare othertert-butoxide compounds such ascopper(I) t-butoxide andhexa(tert-butoxy)dimolybdenum(III):[4]
