Dibenzylideneacetonedibromide (1) gives three different products 2, 3 and 4, when its solution in chloroform is irradiated by electromagnetic radiation at different wavelengths. The structures of these products have been confirmed by spectral analysis or co-TLC and mixed m.p. with authentic samples.
