L. Marx et al., A comparative study of the reduction by ascorbate of 1,1,3,3-tetraethylisoindolin-2-yloxyl and of 1,1,3,3-tetramethylisoindolin-2-yloxyl, J CHEM S P1, 8, 2000, pp. 1181-1182
1,1,3,3-Tetraethylisoindolin-2-yloxyl and its water-soluble trimethylammoni
um and sulfonate derivatives are more resistant to reduction by ascorbate t
han the corresponding tetramethyl derivatives.
