The reaction of α,β-chalcone ditosylates 3 with potassium hydroxide in suitable conditions leads to 1,2-aryl shift and carbon-carbon bond cleavage, thereby providing a novel route for the synthesis of 1,2-diarylethan-1-ones 4 and 1,2-diaryl-3,3-dimethoxy propan-1-ones 5.

C6H5IO/CH3OH and a catalyst such as FSO3H, CF3SO3H or BF3-Et2O as well as C6H5(OH)OTs-CH3OH, react with chalcones, acetophenones and styrenes to yield rearranged products.The overall course of these reactions is analogous to that of Tl(NO3)3-CH3OH in reaction with the same compounds.

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.
