Photocyclization of 2-chloro-substituted 1,3-diarylpropan-1,3-diones to flavones

The photochemical behavior of 2-halo-substituted 1,3-diarylpropan-1,3-dione strongly depends on the nature of the halogen atom bonded and the presence of electron-donor groups on the phenyl ring. In the case of 2-chloro-1,3- diphenylpropan-1,3-dione and 1-(3,5-dimethoxyphenyl)-3-phenylpropan-1,3-dione, cyclization to flavones was the sole reaction pathway, whereas in the case of 2-chloro-1,3-di(4-methoxyphenyl)-propan-1,3-dione, only products derived from α-cleavage were observed. 2-Fluoro derivatives of 1,3-diarylpropan-1,3- diones were photostable; on the other hand, 2-chloro-2-fluoro derivates resulted in 3-fluoroflavones.
