As a tertiary alcohol, tert-butyl alcohol is more resistant to oxidation than the other isomers of butanol. tert-Butyl alcohol is deprotonated with a strong base to give the alkoxide. Particularly common is potassium tert-butoxide, which is prepared by treating tert-butanol with potassium metal. K + t-BuOH → t-BuO K + 1/2 H2
