Abstract The reactions of e aq − , CH 2 OH·, (CH 3 ) 2 COH·, CO 2 ·− , OH· and N 3 · radicals with peroxo terpyridine complexes of Cu(II), Zn(II), and Cu(II)Zn(II) in aqueous solution were investigated by pulse radiolysis. The primary products from the reduction and oxidation of the macrocyclic complexes were assigned a radical nature by comparing their optical spectra with those of Cu(I), Zn(I), and Cu(III) species. Such metal–ligand radical products undergo disproportionation that does not lead to the formation of Cu(0) or colloidal copper. © 2000 John Wiley & Sons, Inc. Int J Chem Kinet 32: 92–98, 2000
