Cyclic voltammetry of a substrate anion-catalyst binary complex intermediate 1> 1); H2salen = N,N'-bis(salicylidene)ethane-1,2-diamine> in a model quercetinase reaction using as catalyst has revealed that the intermediate partly undergoes ionic dissociation in dimethylformamide (dmf) to give L1 and (1+).Dioxygen is then incorporated into the flavonolate anion in a non-radical manner, which is promoted by the counter cobalt cation complex, finally to give 2(dmf)>(HL2 = a depside product) which then forms L2 and (1+).The reaction rate was affected by the nature of the cation employed: (1+) is more effective than K(1+).
