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.
研究了2,2,4,6,7-五甲基库玛兰-5-醇(1)的硝酸银氧化。到目前为止,所收到产品的复杂混合物与部分假定的机制存在部分分歧,因此提出的Mills-Nixon效应要弱于迄今为止的假定。检查了作为主要产物的2,2,4,7-四甲基香豆素-5,6-二酮(2)的连续反应。
