The rearrangement of some β-phenoxyethyl alkyl(aryl) ketones to 4-hydroxyphenoxyethyl alkyl(aryl) ketones has been studied. The latter undergo rearrangement under oxidative conditions to flavilium salts such as 0-trimethylapigeninidin chloride or 0-tetramethylluteolinidui chloride. The mechanism of these changes has been discussed.
研究了一些β-苯氧基乙基烷基(芳基)酮到4-羟基苯氧基乙基烷基(芳基)酮的重排。后者在氧化条件下重排为黄酮盐,例如0-三甲基芹菜碱素氯化物或0-四甲基木犀草碱二氯化物。已经讨论了这些更改的机制。
