Cationic complexes of the type [M(CO)S(PPh3)2]+ (M = Ir, Rh; S = CH3CN) react with singlet oxygen to form the corresponding peroxo complexes [M(CO)S(PPh3)2(O2)]+. The solvent molecule remains coordinated to the metal in the oxygen adducts. The novel cationic iridium-peroxo complex is stable at room temperature, while the rhodium-peroxo complex is only stable below 0 °C. Rate constants for physical and chemical interaction of the complexes with singlet oxygen are somewhat smaller than those for related neutral complexes. Upon addition of alkenes (tetramethylethylene or 1-octene) to the peroxo complexes, neither oxidation of the olefins nor substitution of the acetonitrile ligand was observed. 1-Octene was isomerized to give mostly 2- and 3-octene by the cationic rhodium(I) complex. A cationic indium complex which already possesses a coordinated diene ligand ([Ir(COD)-(PPh3)2]+) did not react with or quench singlet oxygen.
