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-Nixon effect than assumed until now. Consecutive reactions of 2,2,4,7-tetramethylcoumaran-5,6-dione (2), which was received as main product, were examined.

The oxidation of 5-hydroxy-2,2,4,6,7-pentamethyl-2,3-dihydrobenzofuran (1) and 5-hydroxy-2,2,4-trimethyl-2,3-dihydronaphtho[1,2-b]furan (2) in various systems was examined. For 1 the reaction mainly took place at the 6- position. On oxidation with silver
