The [5, 10, 15,20-tetrakis((pentaammineruthenio(II))-4-pyridylporphinato ]cobalt(II) complex that catalyzes the fourelectron reduction of O_2 at graphite electrode surfaces on which it has been assembled has now been prepared in homogeneous solution. The preparative procedure for the catalyst is described, and the kinetics of its catalysis of the reduction of O_2 by chemical reductants in homogeneous solution are reported. In solution, only twoelectron reductions of O_2 are obtained and the rate of intramolecular electron-transfer from the four Ru(NH_3)_(5-)py^(2+) centers on the periphery of the catalyst molecule to an O_2 molecule coordinated to the Co(II) center in the porphyrin ring is shown to be quite slow. Possible reasons for the co...
