Abstract
Upon UV-light irradiation with a high-pressure mercury lamp, methyl 2,4-dioxopentanoate in a mixture of benzene and cyclohexane afforded a crystalline head-to-head[2+2]cyclodimer. Its structure was elucidated by a single-crystal X-ray analysis, as well as 1H and 13C NMR spectroscopy. Ethyl 2,4-dioxopentanoate also gave a cyclodimer.
