Abstract: Changes in the activation parameters of amination along mechanisms S (N) 2, S (N) Ar, Ad (N) and in reactions with acyl group transfer may serve as an additional investigation method for these reactions in solution. The approximation utilizes the substituents effect in benzene and pyridine derivatives on the changes in the activation parameters Delta X (not equal) (X = H, S, G) in the framework of equations of Hammett's type for the estimation of the resulting reaction constants delta I"X (not equal). The single linear dependences of the reaction constants of internal enthalpy delta I"H (int) (not equal) on the reaction constants delta I"G (not equal) and Hammett's rho show that the substituents effect in the leaving and non-leaving groups and in the nucleophiles on the amination mechanisms is governed by the delta I"H (int) (not equal) , when unique stage of the process determines its rate.
