Proton and carbon-13 nuclear magnetic resonance studies of substituted pyridines and pyrimidines: VII-The structure of hydroxy- and mercapto- pyridines and pyrimides from J(HH) and J(CH) values
Accurate values of iJ(HH) and iJ(CH) were obtained for a series of hydroxy‐and mercaptopyridines and‐pyrimidines. It is shown that the 3J(CH) values provide a valuable criterion for differentiating aromatic from quinoidal structures, and is an easy method for determining N‐methylation or N‐addition...
