The colors of autumn leaves appear when chlorophyll is broken down, a process assumed to result in certain colorless degradation products. In their Communication on page 10 724 ff., B. Kräutler and co‐workers report the analysis of fall leaves of Norway maple, in which the typical catabolites were not present. Instead, another colorless compound accumulated, a so‐called dioxobilane, the structure of which indicates a different degradation path in the leaves of this widespread deciduous tree.
