摘要：

Aqueous CH(3)ReO(3)bipy, which is formed by the addition of 2,2'-bipyridine (bipy) to a solution of CH3ReO3, displays a long-wavelength (CH3- --> bipy) ligand-to-ligand charge transfer (LLCT) band at lambda(max) = 360 nm. Light absorption by this band leads to photolysis according to the equation CH(3)ReO(3)bipy + H2O --> CH4 + bipyH(+) + ReO4- (phi = 0.28 at lambda(irr) = 366 nm). As shown in a previous study, the photolysis of the parent compound CH3ReO3 proceeds in a similar manner to the bipy adduct, but requires shorter wavelength irradiation corresponding to (CH3- --> Re-VII) ligand-to-metal charge transfer (LMCT) excitation.
