摘要:

AbstractAccurate values ofiJ(HH) andiJ(CH) were obtained for a series of hydroxy‐and mercaptopyridines and‐pyrimidines. It is shown that the3J(CH) values provide a valuable criterion for differentiating aromatic from quinoidal structures, and is an easy method for determiningN‐methylation orN‐additio
