Abstract : During the course of examination of some pyridine N-oxides and diazine mono-N-oxides, it was observed that whereas the coupling across the nitrogen is negative in pyrimidine N-oxide, the coupling is positive in pyrazine N-oxide. The diazine mono-oxides were prepared according to the literature methods and examined as degassed deuterochloroform solutions. (Author)
