15-fold increase in kd (Chem. Commun. 2011, 47, 4291–4293) was investigated experimentally and theoretically by quaternization of the pyridyl moiety using methylating (MeOTs), acylating (AcCl), and benzylating (PhCH2Br) agents as well as by oxidation of the pyridyl moiety into N-oxide and by the formation of a dative bond with BH3 as a Lewis acid.
