The solvent-initiated photolysis of dichloro(2,2'-bipyridine)platinum(II) in chloroform
Under 254 nm irradiation, [Pt(bpy)Cl2] is converted to [Pt(bpy)Cl4] in a solvent-initiated process. The reaction is very nearly zero order throughout. The rate decreases slightly with increasing starting concentration. These characteristics can be rationalized by a rate law of the form afs, where fs, is the fraction of light absorved by chloroform. The species that reacts with [Pt(bpy)Cl2] is believed to be CCl3OO.
