Abstract
Consideration of the protonation equilibria and rates of quaternisation of substituted pyridines shows that dipolar electron withdrawing groups exert their influence by induction alone; this has an important bearing on the validity of the YT (Yukuwa–Tsuno) and DSP (Dual Substituent Parameter) equations in this system.Keywords
