Formation of cation radicals by pulse radiolysis of metalloporphyrins and chlorophyll a in 1,2dichIoroethane is reported. Demetalation of the metalloporphyrin by radiolytically produced HCl is also observed. Rate constants for demetalation of ZnTPP and Chl a are 1 .I X IO8 and = 3 X IO8 h!-' s-I\_ O
