Pyridofuroxan ([1,2,5]oxodiazolo [3,4-b]pyridine 1-oxide) undergoes isomerization between the N1oxide and N3-oxide forms which can be observed by the 1 H, 13 C and 15 N NMR spectroscopy but not by 14 N and 17 O NMR at ambient and low temperatures. The rearrangement becomes slower at low temperatures

The 17O, 13C and 1H NMR spectra of a number of 1,2-dialkoxyethenes R1OCHxCHOR2 were recorded. The O atoms, in particular those of the E forms, are strongly shielded relative to the 17O nuclei of the corresponding alkyl vinyl ethers Moreover, in compounds of the type ROCHxCHOMe, the di †er-ROCHxCH 2

13C and 17O NMR spectra are reported for three series of Schi † bases : 2-(aminomethylene)cyclohexanones (1), salicylideneamines (2) and N-(2-hydroxy-1-naphthalenylmethylene)amines (3). The 13C and 17O NMR data show that Schi † bases 1 exist in ketoenamine form, 2 in enolimine form and 3 as an equil
