The ruthenium oxo complex electrogenerated from Cis ‐[RuL 2 (OH 2 ) 2 ] 2+ (L = 6,6′‐dichloro‐2,2′‐bipyridine) is an active catalyst for the oxidation of D(+)‐glucose in solution. The second‐order rate‐constant for the reaction between cis [RuL 2 O 2 ] 2+ and D( + )glucose in 0.1 M CF 3 CO 2 H evaluated by rotating disk voltammetry is (1.2 ± 0.2) × 10 2 dm 3 mol −1 s −1 . The chemically modified electrode prepared by immobilization of the ruthenium complex inside a Nafion film on the pyrolytic graphite electrode surface is capable of catalyzing glucose oxidation at potentials comparable to other reported modified electrodes.
