The reaction of alkyl phosphites and thiolphosphoric acids with β-aroylacrylic acids 1a,b has been investigated.Dialkyl phosphites (DAP) attacked 1 at the β-carbon atom with respect to the aroyl-carbonyl function, to give phosphonate 1:1 adducts assigned structure 2A.Thiolphosphoric acids (7) attacked 1 at the same centre to give adducts 8.On the other hand, trialkyl phosphites (TAP) converted 1 into the respective esters 5, almost exclusively.Structures of the new products were assigned according to consistent analytical and spectroscopic measurements.Key words: β-aroylacrylic acids; alkylation; phosphorylation; thiophosphorylation.
