A two-step photoreaction is induced by irradiation of the PtIV complex trans,cis-[Pt(OCOCH3 )2 I2 (en)] with visible light in the presence of guanosine 5'-monophosphate (5'-GMP; see scheme): A photoinduced ligand exchange followed by photoreduction gives the bis-GMP adduct of [Pt(en)]2+ . Although the dihydroxodiiodo complex also undergoes a photoinduced ligand exchange, no reaction with the nucleotide was observed.
