Benzoin oxidation at extreme temperature by bis(1,2-benzenedithiolato)dioxotungstate(VI) complex: A model study for hyperthermostable tungsten oxidoreductases

Article abstract of DOI:10.1246/cl.1996.1131

The oxidation of benzoin by (NEt₄)₂[M^VIO₂(S₂C ₆H₄)₂] (M = W (1) and Mo (2)) (S₂C₆H₄ = 1,2-benzenedithiolate) was studied to clarify the role of tungsten ions in hyperthermostable enzymes. The reaction was analyzed by saturation kinetics, primary isotope effects of k_H/k_D, and the high temperture reaction at 100°C. The rate constants were also compared with those of the selenolato analogs.
