In this Letter, we report reversible addition and elimination of alcohols by acyclic vicinal tetracarbonyl compounds. First, the reversible fixation and release behavior of alcohols by an acyclic vicinal tetracarbonyl compound, 1,4-diphenyl-1,2,3,4-butanetetraone (DPBT) was investigated. On the basis of the results, the addition of alcohol to DPBT was carried out to provide the alcohol adduct of DPBT, which has a hemiacetal structure. Furthermore, we discovered the reaction of DPBT with 2 equi amount of methanol.
