| Abstract: | Photochemical oxidation of 7-methoxy-3-phenyl-2-[(E)-2-(thiophen-2-yl)ethenyl]-4H-chromen-4-one 4 in methanol containing iodine in the presence of air afforded 9-methoxy-5-thiophenyl-12H-benzo[a] xanthene 5. The structure of the photo products was confirmed by IR, UV-Vis, 1H NMR and mass spectra. A suitable mechanism has been proposed. |
