Oxidative rearrangement of chalcones with no free hydroxy group with thallium(III) nitrate (TTN) in methanol was studied in detail and the following results were found.The reactions were greatly accelerated when there were methoxy groups at the 2-, 4-, an

Treatment of chalcones (ArCH=CHCOAr') with thallium(III) trinitrate (TTN) in acidic methanol or in trimethyl orthoformate (TMOF) gives 3,3-dimethoxy-1,2-diarylpropan-1-ones (oxythallation, Ar rearrangement) and/or methyl 2,3-diaryl-3-methoxypropanoates (in situ ketal formation, oxythallation, Ar' rearrangement).The effect of substituents on Ar and Ar' on the ratio of the above rearrangement products has been examined.
