10-(3-Acetamidobenzylidene)anthrone

W. Zhou, W.-X. Hu, C.-N. Xia and M.-Q. Chen

Abstract: The title compound, C₂₃H₁₇NO₂, was prepared by reacting 10-(3-aminobenzylidene)anthrone and acetic anhydride in the presence of pyridine. X-ray crystal structure analysis shows that the three rings of the anthraquinone system are not coplanar because of steric interactions with the benzylidene group.
