General description

1,3-Dibenzoylpropane is a 1,3-diaroylpropane. 1,3-Dibenzoylpropane is formed during hydroxocobalt(III) Schiff base complexes catalyzed selective aldol reaction of dibenzoylmethanes with formaldehyde in methanol.

Application

1,3-Dibenzoylpropane may be used in the electrochemical synthesis of cis-1,2-diphenyl-1,2-cyclopentanediol, via reduction in acetonitrile.
