Article abstract of DOI:10.1016/S0040-4039(99)00483-9

A 2'-deoxyuridine derivative functionalized via an acetylenic junction with a Zn(II) tetraarylporphyrin has been prepared. Is also reported an unexpected in situ bromination of the uracil nucleic base at the C5 position, which occurs during the transforma
