Wavelength dependent photoadditions of 6-cyano-1,3-dimethyluracil to phenylacetylenes are described.Photolysis with Pyrex-filtered light gave the fused cyclobutenes (3,9), whereas irradiation with 254-nm light afforded the rearranged adducts (5,11).The structures of the adducts were established by X-ray analyses.
