Pulse photolysis has been used to investigate the photochemical reactions that take place in the series of oxochloride complexes of Re(VII), Re(VI), and Re(V) in concentrated hydrochloric and sulfuric acids and their mixtures. The kinetics of the formation and decay of the short-lived complex ReOCl 5 have been studied as a function, of the composition of the medium (the concentration of the acids and water). The causes of the stabilization of ReOC 5 in concentrated H2SO4 have been elucidated. It has been found that the anion radical Cl 2 formed in the photolysis of HCl oxidizes the complex ReOCl 5 2− to ReOCl 5 .
