The 1,1-ADEQUATE spectrum clearly shows specific two-bond proton to carbon correlations to unequivocally distinguish the major and minor regioisomers of ortho-halogenated pyridines and to aid in assignment of the corresponding proton and carbon chemical shifts. M06-2X/6-31+G(d,p) free energies of the regioisomeric intermediates arising from deprotonation correctly predict the experimentally observed preference and thus can be used to tune the substituent pattern to yield a desired regiochemical outcome.
Highly Regioselective Halogenation of Pyridine N -Oxide: Practical Access to 2-Halo-Substituted Pyridines

, p. 2948 - 2951 (2015)
A highly efficient and regioselective halogenation reaction of unsymmetrical pyridine N-oxide under mild conditions is described. The methodology provides a practical access to various 2-halo-substituted pyridines, which are pharmaceutically important intermediates.
