2b ) reveals a positive trend, with ρ = 1.46 suggesting a system whose equilibrium properties are dictated by the electronic nature of the β-phenyl substituent. 33 As an interesting note, the apparent downward curvature of the data shown in the Hammett plot was also observed by Anslyn and suggests there may be variability in the overall mechanism of dynamic exchange depending on the electronic nature of the Michael acceptor.
