DISMUTATION
KINETICS OF FLAVINE IN DIMETHYLFORMAMIDE
The Kinetics of Flavine Oxidation-Reduction. I. Dismutation in Nonaqueous Solvent? Vincent Favaudon and Jean-Marc Lhoste*
ABSTRACT: The dismutation reactions of flavines in dimethylformamide have been investigated using the stoppedflow technique under anaerobic conditions. The ionization constants of fully reduced and oxidized tetraacetylriboflavine were measured spectrophotometrically in buffered dimethylformamide. T h e dismutation equilibrium of the flavine as a function of pH in dimethylformamide was roughly comparable to that reported in water and allowed the estimation of the pK, value of the flavosemiquinone. T h e dismutation kinetics of tetraacetylriboflavine in unbuffered dimethylformamide were investigated using the fully oxidized and reduced flavines in their neutral form a t constant product of concentrations and varying the reduction degree. The kinetics a t very low reduction ratios (
