Abstract

Photoreduction reactions of Re(VII) in the presence of an electron donor — diphenylamine (DPA) and hydroquinone (HQ) in concentrated hydrochloric acid solutions — were studied using the pulse photolysis method. The short-lived complex of rhenium(VI) ReOCL5 undergoes one-electron oxidation reactions with both DPA to form a cation-radical DPA+. and with HQ to form a semiquinone radical. The decay of the cation-radicals DPA+. proceeds by a second order reaction with the formation of a stable product (λmax=590 nm)
