Heating 4-allyloxytropones gave Claisen rearrangement products together with oxidation products such as C–C coupling dimers. The products were sensitive to oxygen. Some of the dimeric products were obtained from the cerium(IV) ammonium nitrate-oxidation of 4-hydroxytropones.
加热 4-烯丙氧基
丙酮会产生克莱森重排产物和氧化产物,如 C-C 偶联二聚体。这些产物对
氧气很敏感。其中一些二聚产物是从 4-
羟基丙酮的
硝酸铈(IV)
铵氧化反应中得到的。
