The silver nitrate oxidation of 2,2,4,6,7-pentamethylcoumaran-5-ol (1) was investigated. The complex mixture of products received is in partial disagreement with the mechanisms supposed so far and proposes a less strong Mills–Nixoneffect than assumed until now. Consecutive reactions of 2,2,4,7-tetramethylcoumaran-5,6-dione (2), which was received as main product, were examined.
