Abstract
Abstract The complex Pd II (1,5-COD)Cl 2 (1,5-COD=1,5-cyclooctadiene) shows a long-wavelength ligand-to-metal charge transfer (LMCT) absorption at λ max =342 nm. It is suggested that LMCT excitation generates a COD radical cation and Pd I Cl 2 − in the primary photochemical step. In acetonitrile, a back-electron transfer takes place that leads to the transformation of 1,5-COD to its 1,3-isomer and a solvated Pd(II) complex. In ethanol, the COD radical cation and Pd I are reduced by the solvent, which is oxidized to acetaldehyde. Metallic palladium is formed as a colloid.
