Variation of the activation parameters in the acylation of pyridine with esters and thioesters may be used as a tool for studying mechanisms of acyl transfer reactions in solution. Here, the effect of substituents in benzene and pyridine derivatives on the activation parameters Delta X (not equal) (where X stands for enthalpy H, entropy S, or Gibbs energy G) in terms of an equation analogous to the Hammett equation is used to estimate the reaction constant delta I"X (not equal). The linear dependence of the reaction constant delta I"H (int) (not equal) on delta I"G (not equal) provides an alternative way of assessing variations in the pyridine acylation mechanism when one step of the process is the only rate-determining step.
