ABSTRACT
The reactions of a series of trans-3-[p-substituted phenyl]-1-phenyl- prop-2-en-1-ones Ia-e with p-anisidine and p-nitroaniline IIa,b were studied in methanol, and their reaction rates were measured. The reaction followed a second order kinetics. In addition, the activation parameters delta H* and delta S* for the reactions of both amines were calculated and led to the conclusion of a cyclic multistep mechanism for that amine. Michael addition reaction involving one molecule from each of olefin and amine used. The nucleophilic attack of the aromatic amines IIa,b on olefines Ia-e obeyed Hamett equation
