HIn 1923, Wieland and Wingler suggested that the hydrogen produced in the reaction of formaldehyde with hydrogen peroxide in basic solution is released in molecular form, but not via hydrogen atoms. The proposed mechanism represented the first description of a “concerted” process and has now been confirmed through kinetic analysis, spectroscopy, and quantum‐chemical computations, as demonstrated by G. Litwinienko, H.‐G. Korth, and co‐workers in their Communication on page 9146 ff.
