(i.e. on deprotonation of the second COOH tionalized pyridine, higher pKa values then in 3 were group). Similarly, a eight-fold increase of the lumines- measured for 4 (pKa =5.6) and 5 (pKa =6.02 ... WebAromatic 13C chemical shifts of 4‐ and 3‐substituted pyridine N‐oxides in aprotic and protic solvents are reported and discussed. Changes in chemical shifts caused by hydrogen bonding and protonation are much smaller than those induced by a substituent, and are not related to the pKa values of N‐oxides. Since the effect of hydrogen bonding is not in the …
