1,3-Dibenzoylbenzene is suitable reagent used in the synthesis of 1,3-bis(1-phenylvinyl)benzene (MDDPE). It may be used in the synthesis of polyanionic spin-quintet molecular clusters and ground state undecet hydrocarbon with 10 parallel spins.

?? ??

1,3-Dibenzoylbenzene ([3-(benzoyl)phenyl]-phenyl-methanone, m-Dibenzoylbenzene) is a diarylketone derivative. It has topologically pseudogenerate Π-LUMO′s (lowest unoccupied molecular orbital). Its synthesis from benzene has been reported. Crystal structure studies suggest that its crystals are orthorhombic and exhibit space goup Pbca.
