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.
