Kinetics of electrochemical reduction of 2-carbomethoxy-1,1-dichloro-2-methylcyclopropane by the double mediator system anthracene-PtII, PdII, and NiII complexes of cyclic aminomethylphosphines

Effective rate constants of homogeneous reduction of 2-carbomethoxy-1,1-dichloro-2-methylcyclopropane have been calculated by the polarographic method of determining the catalytic increase in the limiting current of the reduction wave of mediators,i.e., individual complexes of platinum, palladium or nickel with cyclic aminomethylphosphines and their combination with anthracene radical anions. Platinum compounds show higher catalytic activity than palladium and nickel complexes in direct reduction with metallocomplexes. The catalytic activity of a double mediator system for the majority of metallocomplexes is higher than the total catalytic activity of the individual metallocomplex and organic carrier.
