The relative rates of epoxidation by dimethyldioxirane, (1), of a series of 4-substituted (E)-ethyl cinnamates have been studied.The data were treated with the Hammett linear free energy relationship and give ρ = - 1.53 indicating an electrophilic O-atom transfer.Second-order rate coefficients were determined for the epoxidation of (E)-ethyl cinnamate by (1) at several temperatures and the Arrhenius factors were determined, Ea = 14.1 kcal mol-1, log (A/s-1) = 7.41.
