Inductivity was defined as thc reaction constant p, in the equation log (klk,) = pluq, where k and k, are fmt-order rate consmiits for the substitutcd and unsubstituted tosylates, respectively, in 80% EtOH and u? i s the corresponding inductive substituent constant [3].

## Abstract A series of α‐chloro‐ and α‐bromoketimines compounds (1‐9) with different substituents at the α‐position and at the imino group has been investigated by electron impact mass spectrometry as possible precursors of the correspondingly substituted α‐imidoyl carbenium ion, an important clas
