Benzoylacetone is the organic compound with the nominal formula C6H5C(O)CH2C(O)CH3. As a 1,3-dicarbonyl, it is a precursor to many heterocycles, such as pyrazoles.[1] It exists predominantly as the enol tautomer C6H5C(OH)=CHC(O)CH3.[2] Its conjugate base (pKa=8.7) forms stable complexes with transition metals and lanthanides.[3]
