摘要:
The title compound, C27H18N2O2, was prepared from the reaction of the ambidentate anion of 2-phenyl-1,2,3, 4-tetrahydrophthalazine-1,4-dione with 9-bromo-fluorene. The phthalazinone ring is nearly planar, edge-to-face aromatic-aromatic geometry is observed and the fluorenyl moiety is nearly perpendicular to the phenyl ring [88.15(9)degrees].
