Abstract

This letter comments on two examples of numerical results of kinetic parameters which are inconsistent with the experimental data given in the same articles. Since this seems to be a trend in inorganic chemistry articles dealing with the catalytic oxidation of 3,5 di tert- butylcatechol and ortho-aminophenol, we call the attention of editors, reviewers and readers about grossly overestimated catalytic parameters in the literature.
